Steam or GOG

The same twelve games, two storefronts, one date. Sort by whichever column matters to you.

Steam

Valve · prices in GBP · VAT included

  • All twelve games on the list are here.
  • Refund within 14 days of purchase if you have played under two hours; the request is a form, not an argument.
  • Cloud saves, Workshop maps for several games on the list, Remote Play Together for the co-op ones.
  • Games are tied to your Steam account and need the Steam client to run.

GOG

CD Projekt · prices in GBP · VAT included

  • Seven of the twelve are here; the installers are DRM-free, so a copy you download is yours to keep and run without a client.
  • A 30-day refund policy that still applies after you have downloaded and played, within reason.
  • GOG Galaxy is optional. Cloud saves and achievements exist for most of the eight, but you can skip the client entirely.
  • Sales tend to go deeper on the same games; on the day we checked, seven of the seven were cheaper on GOG.

Which store, then

If you want the copy to be yours forever, take GOG where it exists. If you play co-op with friends who all live on Steam, or want Workshop maps, take Steam. On price alone it swings week by week; the sale calendar says when each store tends to cut deepest. Key resellers such as Fanatical, Green Man Gaming and Humble sell Steam keys that are often legitimate and sometimes cheaper, but their refund terms are their own and a key, once revealed, is normally final, so we leave them out of the comparison.
