are there games that only GOG sells?

SSI Goldbox games, some Warhammer games, and some other select few that they own the rights for. There are also a bunch of older games that aren't sold anywhere else like Warcraft 1 & 2 and Diablo.

Please use Google

just curious: is this info important to you for purchasing decisions regarding what to get here vs Steam (and maybe other stores)? Perhaps get as much as possible on Steam to conveniently have it all in one place? (apologies if I come across as rude, btw)

Eh. A bunch of the EA games (most?) are available on Origin.

Well, it's hard to find exclusive games to GOG only, one need to check every other available store including the obscure ones and preferably with VPN for various regions since some games are hidden for different region zones.

I think the Legend of Kyrandia trilogy is one example:

https://www.gog.com/game/legend_of_kyrandia_hand_of_fate
https://www.gog.com/game/legend_of_kyrandia_malcolms_revenge

Goblins trilogy is another:

And AD&D games which were published with the help of GOG's own resources with obtaining certain rights:

There are also a few Warhammer games:

Is DRM Free platforms only. Just gog and itch. The Developer dislikes Steam as much as I do.

There are some old adventure games that aren't on Steam, presumably not anywhere else either.

At least these:


Galador - The Prince and the Coward

Kajko i Kokosz

Teenagent

stranglehold
