recommend some good games please.

i've started building a rig and while i was out today i had a look in my local game and i got 3 pc games for £30 and i brought BF2, BF2142 and STALKER.

can anyone else recommend some good online/single player shooters/RPGS? (my friend is giving me crysis and i have orange box for 360 so those two are out of the question).

sorry if this post seems jumbled I'm very tired.

i thought about gears of war(have the xbox 360 version) is there enough extra content to warrant another purchase?

oh yeah i almost forgot. any forgiving, fun RTS games?(preferablely sci-fi)

quake 4 was terrible on 360 i hear its better on pc though, i download the demo

this has been helpful any other suggestions? :P
