I think it was Dune II? I am not quite sure though

GTA: Vice City.

On PC, some monochrome Pac-Man clone on a PC that didn't even use MS-DOS.

My first game for any system was something I can't name on a Sega SG-1000.

Damn, I don't even remember. ._.

Dune 2000 and Heroes of Might and Magic 2 :)

Those trial discs that used to come for DOS games, would be something like Return to Zork, Secret of Amen Ra, King's Quest, and Might & Magic all on one CD. I also recall Need For Speed (no subtitle, LAWLZ) quite fondly from my first PC playing years. My first ever game purchase for was a sick robot-fighting game called One Must Fall, I think they have some online iteration of it now.

some tanks game similar to worms....it was a lot of fun :D

Would you call the Commodore 64 a PC? If so, then it was probably International Karate +.

Solitaire.

this one or maybe this

WOW

Scorched Earth. Ah, the memories....

Half Life. Remember it clearly, i was console only before. Didn't know what kind of game it was, it was our first computer at home, and my uncle gave us somes pirated games burned on CD.

An old 5.25" floppy disk batman game.

Quake.

Sonic the Hedgehog 3

Duke Nukem 3D
