Windows Pinball. Don;t play any other games anyomore...
Used to love Fallout (esp 2) and GTA Vice city (though I HATE cars, music in that game was soo great that it was worth playing).
SNES games on the other hand
EDIT- actually this thread makes me think that maybe I should play some games again...Tomorrow will ask my bro who is a huge gamer does he has anything interesting...By now, Im launching Pinball..
