PS1
1. Tekken all of em. i suck at these too but there fun.
2. Grand trismo 1 and 2. Fun games, it's hard to go drive in real life after playing.
3. Mortal Kombat. Blood and more blood
Game Cube.
1. Zelda the wind Wacker
. Gfx suck, i'm not a fan of cell shadding but the game it's self is fun on my 3rd time through it.
2. SC2. fun game. espechial when you play for shoots, and have like 5 or 6 5th's and a case of beer, Needless to say i'm the only one who can stand up after playing it for 3 or 4 hours.
3. Tony Hawk pro skater 3. It's fun when yer board.
PS2
1. Grand theft auto all of em. (it's fun to drive around after a stressfull day and commit mass murder)
Thats all i can think of right now and that list is huge as it is. The only gripe i have with newer games is that GFX is the biggest pusher and i like games with more depth to them. Graned the GFX are cool but i'm old skool. and the other thing that newer games focus on is Online game play, Never was a fan of it. i don't like haveing to play with other people to get my enjoyment.
