How Much Disk Space Do Free PC Games Really Need?

You are choosing between two free-to-play games and your drive has room for one, not both. Steam's own listing already tells you the floor each one needs before you start, and GamiPrime has already read that number for 17 free PC games across its Hardware coverage. This guide lines those numbers up, then explains why the figure you see on the store page is often not the number your drive ends up holding a few months later.

Why this matters before you pick a game

A free-to-play game needing 50 to 150 GB is common, and a listed minimum is a floor, not a forecast. Finding out halfway through that a game needs more room than your drive has left wastes an evening. Checking the number first, and understanding what it does and does not promise, takes a few minutes.

GamiPrime has not benchmarked or tested any of the 17 games below for this guide. Every figure is copied from a GamiPrime Hardware article that already read the game's own Steam store listing on a stated date.

Storage compared across 17 free-to-play PC games, smallest minimum first

Sorted by the smallest listed minimum, MU: Dark Epoch needs the least room (800 MB) and Wuthering Waves needs the most (150 GB). Each row is sourced to the specific GamiPrime Hardware article that reported it: the Hardware pillar for games it covers directly, or that game's own dedicated Hardware satellite where one has since been published.

Albion Online's Windows minimum is used above because that is the only platform tier with a storage figure in its own listing; its Mac tier gives no storage number at all, and its Linux tier gives a recommended figure (8 GB) with no matching minimum. The other 16 rows are each game's single published figure, as GamiPrime's own Hardware coverage reported it.

What "minimum" and "recommended" do not promise

A recommended figure is not always the minimum plus a safety margin, and four of these 17 games do not list one at all. MU: Dark Epoch, Project Entropy, Warframe and Albion Online's Windows tier each stop at a minimum, with no recommended storage line on the store page GamiPrime read. Treat "no recommended figure" as "unconfirmed," the same caution Steam's own missing fields get elsewhere on GamiPrime: not a promise that the minimum is all you will ever need.

Where a recommended figure does exist, it is not always the same as the minimum. Nine of the 13 games that list both figures show an identical minimum and recommended storage figure, what GamiPrime's Hardware coverage has elsewhere called a "zero-gap" tier. The other four do not: Infinity Kingdom lists 4 GB against a 2 GB minimum, RAID: Shadow Legends 8 GB against 5 GB, War Thunder's recommended tier asks for 95 GB against a 70 GB minimum, and Where Winds Meet jumps from 130 GB minimum to 200 GB recommended, the largest gap in this table. Neither publisher explains the difference on the listing; it is simply the number the recommended tier lists.

Check this: before you assume a game's listed minimum is close to what you will actually need, open its recommended tier too. A flat, unchanging number across both tiers is common in this table, but it is not guaranteed.

The Zenless Zone Zero case: when the first batch of files is not the full picture

Zenless Zone Zero's Steam page lists 75 GB of required space, but the initial files GamiPrime's own coverage reported were smaller: 68.3 GB. GamiPrime's News coverage reported this directly, citing KeenGamer's June 17, 2026 account of the Steam launch: Steam's listing shows 75 GB, and the game's launch-day files came in under that figure, with more data arriving after the player first logs in.

That gap runs the opposite direction from what you might expect. The number you see before you start was not the full footprint the game eventually asks for; the smaller, faster first batch of files is a starting point, not the final size, because the game keeps pulling data after you are already inside it. GamiPrime has not tracked how large Zenless Zone Zero has grown on disk since that June 2026 launch; the only verified figures are the ones reported at the time.

Common mistake: reading a game's listed minimum as the one number that matters, then being surprised when your drive fills further after you have already started playing. The listed figure is what the publisher asks you to have free before you start, not a cap on how much space the game will eventually use.

Why free-to-play games tend to grow after launch

Live-service games that run on seasons, patches and ongoing content drops are widely reported, across the games industry generally, to add to their size on disk over time rather than stay fixed at launch. This is a general pattern reported across many live-service titles, not a GamiPrime-verified figure for any specific untested game here; this guide does not assign a growth percentage to any of the 17 titles in the table above beyond what the Zenless Zone Zero case already documents.

What drives this, in general terms widely understood in PC gaming: new areas, characters, maps or seasonal events each add their own assets; some games keep older seasonal content on disk for players who want to replay it rather than removing it; and patches themselves add new files without always fully reclaiming the space used by what they replace. None of this is specific to one GamiPrime-tracked game; it is why planning for "the listed minimum plus room to grow" tends to serve a player better than planning for the exact number on the page today.

If that does not work: some live-service games also split per-language voice packs, letting you choose which language's audio to add separately from the base game. This is a general mechanic reported across live-service PC games broadly, not a confirmed feature of any specific title in the table above; if a game you are setting up offers a language selection screen, check it before assuming the base files are the whole footprint.

A checklist before you commit drive space to a free game

Four checks catch most storage surprises before they happen, and all four take less time than one failed setup.

• Do this: check both the minimum and the recommended storage figures on the live Steam page, not just the first number you see. As the table above shows, they are not always the same, and not every game lists a recommended figure at all.
• Check this: look for a language or voice-pack selection during setup or first launch. Some live-service games let you skip audio languages you do not need, which can reduce (or, if you add a language later, increase) the footprint from what the base listing shows.
• Common mistake: filling your drive with a game right up to the last free gigabyte, with no margin for patches. The Zenless Zone Zero case above shows files that grew after the player logged in; leaving headroom beyond the listed minimum avoids a drive that is full before a single update lands.
• If that does not work: if a game is already on your drive and you are running low on room, check its own launcher or Steam's storage manager for optional content you can remove separately, such as older seasonal assets some live-service games keep by default. Not every game offers this; GamiPrime has not verified which of the 17 titles above do.

Before you start comparing drive space, GamiPrime's guide to how free-to-play PC games make money covers the in-app purchase flags that typically sit next to the storage and controller lines on the same Steam listings.

Frequently asked questions

Which free-to-play PC game needs the least storage?

By listed minimum, MU: Dark Epoch needs the least at 800 MB, per GamiPrime's Hardware pillar. Albion Online's Windows tier is next at 2 GB, tied with Infinity Kingdom.

Which free-to-play PC game needs the most storage?

Wuthering Waves lists the largest minimum in this table at 150 GB, with an equally large 150 GB recommended figure, per its own GamiPrime Hardware satellite.

Does a game's size on disk stay the same after launch?

Not necessarily. Zenless Zone Zero's own launch-week figures, reported by GamiPrime's News coverage, show initial files (68.3 GB) smaller than its listed requirement (75 GB), with more data arriving after the player logs in. Live-service games in general are widely reported to add content after launch through patches and seasonal updates, though this guide does not attach a growth number to any other specific title.

Should I trust the "minimum" number alone when planning storage?

Treat it as a starting point, not a full plan. Four of the 17 games in this table list no recommended storage figure at all, and two that do list one well above their minimum (War Thunder, Where Winds Meet). Leaving room beyond the listed minimum protects against both cases.
