One huge gamer here! First introduction into the world of games and pcs were at a very young age via my 10 years older brother. My parents had bought him a commodore 64 when those things were fairly new. It even was one of those older models with the games being in cassette tapes.

Then a few old pcs like 386 and 486, there was one pc before those but I can't remember what it was. It did have few games I can still remember, The art of war and one strategy/action game placed in medieval britain.
Oh man, I still remember how wolfenstein 3D, Doom, Jagged Alliance and the likes were the absolute top in the game world.
Few of my all time favorites in no particular order;
Fallout 1&2 (The best rpg games ever, hands down!)
Elder scrolls: Arena (Couldn't finish the game because of them damn riddles!

)
Doom (played it in coop mode countless and countless hours with my best friend in LAN. Still is one of the most entertaining coop games ever made.)
Duke Nukem 3D (Same thing as with Doom, coop ftw!)
Jagged Alliance series (A legend! Still play JA 2 from time to time)
Civilization series
Pretty much every adventure game made by Lucasarts during the 90s (Day of The Tentacle, anyone?

)
Warcraft 1&2 (2 in LAN with a friend, ain't better thing in life!)
Dune 2 (The father of all real time strategy games)
Half-Life (FPS genre has never been the same)
Ufo - Enemy unknown (An incredible game!)
Countless others.. Way too many to list
Haha, I sometimes wonder how I've managed to do anything else besides play games.
