How many hours does it take to complete the main story of the largest open-world games in 2027?

Two ways to read a completion time: critical path versus completionist

Every hour figure attached to an open-world game is answering one of two very different questions, and confusing them is the single biggest reason people feel misled by a number they read before buying.

The first reading is the critical path — sometimes called "main story," "main quest," or "campaign." This is the shortest defensible route from the opening cinematic to the credits, doing only the quests the game gates progression behind. A critical-path run assumes you skip optional dungeons, ignore collectibles, do not grind for gear beyond what the game hands you, and accept whatever difficulty the default setting gives you. In the largest 2027-era open-world titles, this number typically lands somewhere in the 30 to 60 hour band. A sprawling action-RPG with a heavy narrative spine sits near the top of that; a more mechanically-driven open world with a thinner story spine can land closer to 25 or 30.

The second reading is the completionist run: every side quest, every map marker, every shrine or tower or outpost, every crafting tree maxed, every achievement unlocked. That number is almost always somewhere between two and four times the critical-path number. A game with a 40-hour main story routinely posts 120 to 160 hours for full completion, and the very largest ones — the ones with procedurally seeded content or live-service tails — can post numbers that are functionally unbounded because the content set keeps growing after launch.

Between those two poles sits the reading most players actually experience, which trackers usually label "main + extras." This is a critical-path run plus the side content you naturally drift into because it is on the way, because a character you like asked you to, or because you needed the gear. Empirically, main + extras usually lands about 1.5x to 2x the pure main story: a 40-hour campaign becomes a 60 to 80 hour playthrough. If you are trying to predict how long *you* will take, this is almost always the right column to look at, because very few players who buy a large open-world game actually beeline the critical path. The habit of checking a map marker two hundred meters off your route is what turns 40 into 70.

There is a fourth, less-discussed reading worth naming: the speedrun time. Community speedruns of large open worlds frequently land under 10 hours and sometimes under 2, because they exploit sequence breaks, movement tech, and skipped cutscenes. This number is real but tells you nothing about your own experience. It is worth mentioning only because it occasionally leaks into casual discussion and makes a game sound far shorter than it plays.

The practical takeaway is that "how many hours does it take to complete the main story" only has a stable answer once you have fixed which of these four definitions you mean. When a number seems wildly off from what you experienced, the definition mismatch explains it far more often than the game changed.

How to decide which number applies to you

Picking the right estimate is less about the game and more about honestly classifying your own play style, your available session length, and how the specific game structures its optional content.

Start with session length, because it dominates everything else. A player with two-hour weekend sessions and a player with 30-minute weeknight sessions do not experience the same 40-hour game. Open worlds carry a fixed re-entry cost — reorienting on the map, remembering the active quest, re-acquiring the control feel — that runs roughly 3 to 8 minutes per session. At 30-minute sessions, that overhead is 10 to 25 percent of your playtime, and a nominal 40-hour campaign realistically consumes 45 to 50 hours of wall-clock time. At two-hour sessions, the same overhead is under 5 percent and effectively disappears.

Second, classify your exploration reflex. The honest test is: when a question mark appears on the minimap 300 meters off your route, do you go? If the answer is always, use the completionist column. If the answer is usually, use main + extras. If the answer is only when the game forces it, use the main story column. Most people underestimate themselves here by roughly one tier.

Third, check whether the game has hard progression gates. Some large open worlds gate the next main quest behind a level, a gear score, or a count of completed side objectives. When that gating exists, the "main story" number is a fiction — you cannot actually run the critical path without doing the side content the gate requires, and the real floor is closer to main + extras. Games without gates let you genuinely beeline, and those are the ones where the main story figure is trustworthy.

Fourth, account for difficulty setting. Moving from default to the hardest tier typically adds 20 to 40 percent to total time in combat-heavy open worlds, concentrated entirely in boss encounters and set-piece fights. On the lowest difficulty, expect to shave 10 to 20 percent. This is a bigger swing than most people expect and it compounds with exploration reflex, because dying repeatedly at a gate pushes you toward grinding side content for gear.

Finally, consider what you are actually optimizing for. If you are deciding whether to buy, the relevant number is main + extras, because that predicts your real engagement. If you are deciding whether you can finish before a deadline — a sequel launching, a subscription lapsing, a friend group moving on — the relevant number is the main story figure plus 15 percent of slack, because deadline runs are the one case where people genuinely do beeline.

Concrete numbers behind each reading

The bands below reflect how the largest open-world releases of this era distribute. They are ranges, not precise per-title claims, and the right way to use them is as a sanity check on any specific number you encounter.

Main story, 25 to 35 hours. This is the shorter end for a game marketed as a large open world. Titles here usually have a tightly authored narrative spine, a map that is dense rather than vast, and relatively few progression gates. Sessions to finish at two hours each: roughly 13 to 18. Weeks to finish at four hours per week: about seven to nine.

Main story, 35 to 50 hours. This is the modal band and where most flagship open-world action-RPGs land. Expect 20 to 25 two-hour sessions, or roughly three months at four hours per week. Main + extras for this band typically runs 60 to 90 hours; completionist typically runs 110 to 160.

Main story, 50 to 80 hours. The large end. Games here usually combine a long authored campaign with substantial mandatory traversal — you spend real time simply moving between objectives. Traversal is the underrated cost driver: in a genuinely large map, 15 to 25 percent of a critical-path run can be movement, even with fast travel unlocked, because fast travel points must first be discovered on foot. At four hours per week, this band is a four to five month commitment.

Main story, 80 to 120 hours. The genuine outliers, and much rarer than internet discussion suggests. This band is mostly occupied by JRPG-descended open worlds and games with long mandatory grind loops embedded in the critical path. Treat any claim in this range with mild skepticism until you confirm which definition is being used — a large share of 100-plus-hour claims are actually main + extras numbers being reported as main story.

Some scaling factors worth holding onto. Fast travel availability changes total time by 10 to 30 percent depending on how early it unlocks and whether it costs resources. Cutscene volume in narrative-heavy titles can account for 5 to 12 hours of a 40-hour run, which matters if you skip them on a replay. Mount or vehicle speed and the presence of a glider or grapple change traversal cost more than almost any other single design choice. New Game Plus runs typically take 40 to 60 percent of a first run, because you keep gear, know the routes, and skip cutscenes.

One more calibration: crowd-sourced completion trackers, which are the most common source for these figures, are self-reported and skew toward engaged players who bothered to log a time. That population finishes games more often and plays them more thoroughly than the average buyer. In practice this biases the "main story" column slightly low — because the people logging main-story-only times are frequently efficient players — and biases the completionist column high. A reasonable correction is to add about 10 percent to any main-story figure you read if you are a first-time player of the series.

Building a realistic schedule and sequencing your run

Once you have a number, the useful next step is turning it into a plan, because the most common failure mode is not misjudging the hours — it is misjudging the calendar.

Step one: convert hours to weeks, not days. Take your chosen estimate, divide by your realistic weekly play hours, and add 20 percent. The 20 percent covers the weeks you miss entirely. A 45-hour main story at six hours per week is 7.5 weeks nominal, so plan for nine.

Step two: decide your side-content policy before you start, and write it down. The three workable policies are: strict beeline (side content only when a gate forces it), radius rule (do side content within a fixed distance of your current objective, ignore everything else), and region sweep (fully clear each region before advancing the main quest, which is the completionist path in disguise). Picking one in advance is what actually keeps a run on schedule; drifting between them is what turns a planned 45 hours into an abandoned 70.

Step three: front-load the traversal unlocks. In nearly every large open world, there is a movement upgrade — a mount, a glider, a fast-travel network, a speed skill — that materially cuts every subsequent hour. Detouring 90 minutes to secure it at hour five routinely saves five to ten hours across the rest of the run. This is the one side-content exception a strict beeline should always make.

Step four: audit at the one-third mark. After roughly a third of your estimated hours, compare your actual main-quest progress against the fraction of the campaign you have cleared. If you are at 15 hours of a nominal 45 and only a fifth of the way through the story, your effective multiplier is about 1.7 and your real completion time is closer to 75 hours. Adjust the plan or tighten the side-content policy then, not at hour 40.

Step five: handle the endgame gate deliberately. Many large open worlds place a level or gear requirement immediately before the final act. If you have beelined, you will hit this wall. Plan for it: budget three to six hours of targeted side content near the end rather than being surprised by it, and prefer high-density content — a region's worth of contracts or a single long optional dungeon — over scattered map markers, because density is what makes those hours efficient.

A note on how to handle multiple games. If you are working through a backlog of large open worlds, the sequencing that works is shortest-first, not most-anticipated-first. Finishing a 30-hour campaign builds the momentum that carries you through a 60-hour one; starting with the 60 and stalling at hour 25 tends to end the backlog entirely. Interleaving two large open worlds at once is the reliably worst option, because the re-entry cost described earlier applies twice and compounds — you spend the first ten minutes of every session remembering which map you are on.

Where published hour counts go wrong

Understanding the failure modes makes you much better at reading any specific number you encounter.

Definition drift is the dominant error. A figure quoted as "main story" is frequently a main + extras figure that lost its label somewhere in a chain of aggregation. If a number seems 50 to 80 percent higher than comparable titles, definition drift is the most likely explanation.

Pre-release developer estimates are systematically unreliable in both directions. Developer-stated campaign lengths are given before final balancing and often reflect internal playtests by people who know the game perfectly. They can be too low for that reason. They can also be too high when the number is being used as a marketing signal of value. Wait for post-launch community data.

Small sample sizes early after launch. In the first week, tracker medians are built from the fastest players, because they are the only ones finished. Those medians typically rise 15 to 30 percent over the following month as ordinary players complete their runs. Checking a completion figure during launch week and treating it as settled is a common mistake.

Content updates move the target. A game that shipped with a 40-hour campaign and later added a story expansion may be reported at 55 hours by sources that fold the expansion into the main figure. Always check whether a figure is base-game or base-plus-DLC.

Platform and performance differences. Loading times, frame rate, and traversal responsiveness meaningfully change total hours between platform versions of the same game. On a title with long loads and frequent deaths, the gap between the fastest and slowest platform can reach 10 percent of total run time.

Your own estimate of yourself. The most common error is not in the published data at all. Players consistently predict they will beeline and then do not. If you have a history of finishing large open worlds well over the quoted main-story time, apply that personal multiplier rather than trusting the column.

Related questions

Does the largest map always mean the longest main story?

No. Map size correlates weakly with campaign length. A vast map with sparse objectives can have a shorter critical path than a dense, smaller one, because main-quest count drives story hours while map size mostly drives traversal time and optional content volume.

How much do side quests actually add?

Typically 50 to 100 percent on top of the main story for a natural playthrough, and 150 to 300 percent for full completion. The variance depends heavily on whether side content is authored questlines or repeatable map-marker activities.

Is the main story figure trustworthy for gated games?

Less so. When a game requires a level or gear score to advance the campaign, the published main-story number often quietly includes the grind needed to pass those gates, or it excludes it and understates your real time. Check for gating before trusting it.

How much faster is a second playthrough?

New Game Plus runs generally take 40 to 60 percent of a first run. You retain gear and knowledge, skip cutscenes, and stop exploring. On a 45-hour campaign, expect roughly 18 to 27 hours.

Should I count cutscene time?

Yes for a first run — it is real time in your chair, often 5 to 12 hours in a narrative-heavy 40-hour campaign. Exclude it when estimating a replay, since most players skip cutscenes the second time through.

FAQ

What is a reasonable single number if I only want one?

About 40 hours. That is the practical median for the main story of a flagship large open-world release in this era, and it is the right default to plan around when you have no title-specific information. Adjust upward if the game is known for a long campaign or hard progression gates.

Why do two sources give completely different hour counts for the same game?

Almost always a definition mismatch — one is reporting the critical path and the other main + extras or full completion. Secondarily, sample timing: figures collected in launch week skew low because only fast players have finished. Check the label and the date before comparing.

How long does full completion take relative to the main story?

Two to four times as long. A 40-hour main story typically maps to 110 to 160 hours for 100 percent completion. Games with procedurally generated or live-service content do not have a meaningful completion number at all, since the content set keeps expanding.

Does difficulty setting really change total hours much?

More than most people expect. The hardest tier commonly adds 20 to 40 percent, concentrated in bosses and set pieces, and it indirectly adds more by pushing you toward grinding for gear. The lowest tier typically saves 10 to 20 percent.

How do I estimate my own time rather than the average?

Take your last three completed open-world games, divide your actual time by the published main-story figure for each, and average the three ratios. That personal multiplier — often between 1.3 and 2.2 — applied to any new title's main-story number will beat any published estimate for predicting your own run.

What actually makes some open worlds take 80 or more hours?

Three things in combination: a long authored campaign with many required quests, high traversal cost from a large map with limited or late fast travel, and mandatory progression gates that force side content onto the critical path. Any one alone rarely pushes a game past 60.
