If you like single player FPS get resistance. UT3 is focused in multiplayer online play (Resistance also have an excelent online multiplayer option). I don´t have played warhawk, so I can´t give you any advice on this game.

P.D. Sorry for my awfull english, I´am from Peru (I speak spanish) Come and visit macchu picchu!!!

I have the 80g + motorstorm pack. It´s awesome!!! I own a copy of ressistance and oblivion. Can´t wait for MGS4, FFXIII and FFVIII vs., Tekken 6, Street Fighter 4, and a loooong etc. Greetings from Peru.
