First game was Fallout 1 & 2, around the time GoG opened its doors.
They were truely hard to find at the time, and GoG was the only way to procure these kind of games which had completely disappeared from the stores (physical, we weren't there yet for the digital ones), which everybody knew, talked about, but many players had missed because too young at the time they released.
The actual first game on my library at GoG is Tyrian 2000 followed by Kid Agent but at the time them and a few others were givaway for registering or buying your first actual game.
ah, yes, nice giveaway. gog galaxy don't have option to list by date purchase and i connected epic games account so i don't know. maybe i didn't buy from you any game yet, i'm mostly buying from other company, will not mention it here.
My first game ever on GOG was Treasure Adventure Game, lmao, but looking through them all I got to say that my favorite is Indiana Jones and the Emperor's Tomb which I'd love to see in the Spanish language since that was the version I played as a kid 🥺
Not sure if this counts but, I've never bought anything on GOG before, but I'd love to one day. If there are any good deals or anything, I'd buy something. I've heard nothing but good things about GOG.
