Need a new game

Ok, so all my friends are off playing GTA4, i dont have an xbox, so i've been playing GTA3 a bit. however, i think it's time for me to get a new game. Idk if i want a shooting one or a RTS. Or even a RPG of some sort. I like star wars (theres a few games i havent played.) i've played wc3, i have COD4, andi have CS:S. I'm just kind of tired of them. what's every1 playing these days and what's good?

Some suggestions:

Bioshock.
Assassins Creed.
The Witcher
The soon to be, Far Cry 2

Command and conquer 3 Tiberium Wars + Command & Conquer 3: Kane's Wrath
Unreal Tournament 3

Been playing WC3 for a couple of years now... ahha

I'm a huge fan, can't wait for Starcraft II later this year (hopefully!!) :-)
