Where to Buy PC Games Cheap: Steam vs GOG vs Epic vs Key Resellers

A practical comparison of the main PC game stores — Steam, GOG, Epic Games Store, and key resellers — and when to use each one to get the best price.

Steam

Steam is the dominant PC gaming platform. Its catalog exceeds 50,000 titles. The ecosystem — Workshop mods, cloud saves, family sharing, community reviews, and trading cards — is mature and integrated in ways competitors have not matched.

On pricing, Steam runs four major seasonal sales per year and frequent publisher-specific promotions. Prices on Steam are also reflected on authorized key reseller sites, so you can often buy a Steam key cheaper elsewhere without touching Steam’s storefront directly.

Downsides: Steam uses DRM (Steamworks). Games are tied to your account. If your account is compromised, suspended, or Valve shuts down, you could lose access. That last scenario is theoretical but non-zero. Steam also does not allow reselling games.

GOG

GOG (Good Old Games) is the home of DRM-free PC gaming. Every game sold on GOG includes a standalone installer — no client required, no activation server dependency, no expiry. You download the file and it is yours.

GOG’s Galaxy client is optional. You can use it for achievements and cloud saves, or ignore it entirely and manage your games manually. For older titles, GOG often includes compatibility patches that make games from the 1990s and 2000s run correctly on modern hardware.

The catalog is smaller than Steam’s but includes most major indie titles and an excellent classic game library.

Best for: People who care about true ownership, offline play, long-term preservation, or who distrust platform lock-in.

Epic Games Store

Epic’s storefront is the newest of the three and the least polished. Mod support is absent. User reviews were only added recently. The launcher is considered intrusive by many users. The catalog is growing but still significantly smaller than Steam.

There are two compelling reasons to use Epic:

Free weekly games. Epic has given away one or more games every week since 2018. Claimed games are yours permanently. The quality has included GTA V, Control, Death Stranding Director’s Cut, Civilization VI, The Outer Worlds, Alan Wake, and hundreds of others. If you are not claiming free Epic games weekly, you are leaving significant value behind.

Timed exclusives. Some games release on Epic first, months or years before appearing on Steam. If you want to play a title at launch and it is Epic-exclusive, you have no choice.

Best for: Claiming the free weekly game and picking up Epic-exclusive titles.

Authorized key resellers

Key resellers sell platform keys (usually Steam) at prices that often undercut the primary store. The critical distinction is authorized vs. gray market.

Authorized resellers buy keys directly from publishers or through licensed distribution channels. The chain of custody is clean. Reputable authorized stores include:

  • Humble Bundle — Pay-what-you-want bundles, charity component, and a regular storefront with solid sales.
  • Fanatical — Frequent bundles and flash sales, direct publisher relationships for most major titles.
  • Green Man Gaming (GMG) — Long-established authorized retailer, competitive prices on new and back-catalog titles.
  • Gamesplanet — Strong for European publishers, frequently undercuts Steam.
  • DLGamer — Smaller but reputable, worth checking for specific publishers.

Buying from authorized resellers carries essentially the same risk as buying directly from the platform. Customer support exists if something goes wrong.

The gray market

Sites like G2A and Kinguin are key marketplaces where individual sellers list codes. The marketplace does not verify where keys came from.

The core problem: a common source of gray market keys is bulk purchases made with stolen credit cards. The fraudster extracts the keys and lists them for sale. When the card owner files a chargeback, the keys get revoked — and buyers who purchased those keys lose their games. Publishers (especially small indie developers) also bear financial liability for chargebacks they receive.

Independent developers have written publicly about this. Some publishers (CD Projekt Red, Team17, and others) have explicitly said gray market purchases do not support them and carry active risks for buyers.

CDKeys sits in an unusual position. It sources keys primarily through regional pricing arbitrage rather than stolen card purchases, making revocation much rarer. Most experienced PC gamers treat it as acceptable-risk for established games. It is still not an authorized retailer, which matters for new releases and account safety.

Regional pricing

Steam charges different amounts by region. A game might cost $60 in USD and $8 in Argentine pesos. Using a VPN to purchase at regional prices violates Steam’s Terms of Service and can result in region-locked licenses, account warnings, or bans. The savings are not worth risking a library you have spent years building.

Which to use

  • General purchases: Compare Steam and authorized resellers (Humble/Fanatical/GMG) and buy whichever is cheaper.
  • DRM-free or offline gaming: GOG.
  • Free games: Claim Epic’s weekly giveaway every Thursday.
  • Key deals: Authorized resellers only. Avoid G2A and Kinguin. CDKeys is manageable for older titles.
