Hmph.... Where to start and where to finish!? I'll edit this post later and write down my favorite games, but right now i don't have the time , so: I play pretty much everything except RTS games. Never really played RTS games. Not sure if I like/dislike 'em or not. :D
EDIT: Yay finally remembered to finish this post.
So here we go:
I mainly play on PS3 now. I used to game on PC as well, but it got fucked up from viruses :/
PS3( i got the 60gigs version so I can play PS2 and PS1 titles as wel :D):
Metal Gear Solid Series. I currently own 1,3 and 4. MGS 3 is the best game ever....EVER!!!
Uncharted Series. Probs one of my fav series ever.
CoD Series. Kinda sick of CoD right now. Blacks Ops is fun, i've played at a friend's. CoD4 is the best one.
Battlefield Bad Company 2. THE ULTIMATE 1ST PERSON SHOOTER! The realism, the huge maps, the need to be tactical, the need to be a team player... Great game. :D
Red Dead Redemption. Looking forward to buying Undead Nightmare expansion pack... :D :D :D :D :D :D :D
Kingdom Hearts Series. One of my fav series. The story is just sooooo good. If you like Final Fantasy try it out :P
Some racing games. Fan of the GT series. NFS is meh. Still fun sometimes though.
Splinter Cell Series. I currently own only Pandora Tommorow, but I have played all except Conviction.
Used to play CoD4. i was really good at it too. Now my PC will explode if I try to re-install it XD
