GameRager: Yes SP is mainly the same maps as well, but at least it has a story I can follow along with and goals I can meet at my own pace, minus the bloody morons who fill such servers.
klaymen: Story? The last time when I played FPS with at least passable story was.....uh......long time ago. Sure, I did not play every modern FPS (due to my crappy PC) but in those which I played, the story (or what passes for it) was not between the reasons why I played them.
Well I never said it had to be oscar worthy material. :)
