A great deal of Snes games
and usually these from time to time :
-Arcanum
-Sacrifice
-Call of Duty 1
-Sim City 4
-Carmageddon 1
-Carmageddon 2
-Serious Sam 1st Encounter
-Serious Sam 2nd Encounter
-Baldur's Gate 2
-System Shock 2
-Broken Swords 1 ( every two years approximately )
-Max Payne 2 ( one of my all-time favourites, perfect gameplay, story, characters, charisma, physics...It had everything )
-Raze's Hell ( best coop experience...EVER )
-Daggerfall ( even though I really like this game, I never managed to get very deep in the main storyline, I always get distracted from it and start exploring these huge, randomly generated and ugly lands.
And probably a lot of of other games I cannot think of at the moment.
