The first damned one.

Some sort of Microsoft file explorer disk with hundreds of games from the 90s and maybe 80s. It had Duke Nukem 1 plus lots of other stuff like DOG (aircraft battles).

pinball, solitaire, and minesweeper...

Super Mario, Prince of Persia, Puzzle Bobble, Prehistorik and Sim Farm, all of these for DOS... Good times :D

Hmm, first PC game ever... It was probably one of those games I got in a cereal box or something. That or it was Diablo II, which is the first game I remember playing. Well, of course, there's no way I wouldn't remember such an awesome game. It was some game where you used math to play most parts of the game. It was pretty cartoony, can't really remember the name. I think I have the CD of it still around somewhere.

Commander Keen in 1993.

i cant remember something on my old commodore
