R:FoM only fps that i actually like playing by myself online or with friends.
runner up is red faction 2 i don't know if many ppl like it but it was a good game, and i hope some deschebag doesn't come along and say halo or ima be ****ed
Playing FEAR at the moment, but its definately not the best.
Suprisingly the most fun i had was C&C: Renegades. I dont think it was the best game, but muliplayer had alot of teamwork and was actually very of social...my god i sound like a nerd.
i really didnt like bf2142. but my favourite would prob have to be... actually i cant think of any. never got round to playing cs:s and that although ive heard so much bout it.
