Heres a rundown.

SP - Short, a LOLWUT? story, lots of guns and explosions and some furious AI chokepoints. (You need luck and lots of it to get through)

MP - The only thing i hate is p2p match up but it works ok so far. 9v9 doesn't make it a fragfest but maps can be bigger right? Oh might I add more gun customization!!!

I haven't tried Spec-ops mode but this game is MP core with SP tacked onto it. If you plan to buy it for SP don't. I really regret buying this on PC but then again I can't play shooters for the life of me on consoles...

Q6600 @ 3.2ghz 4gb ram 4870 512mb gpu w/ vista 64bit... Seems to run fine. Only thing i hate about it is the rendering glitches on slopes. And I can't set rendering on high :P

Freespace 3

Shogun: Total War

Grim Fandango 2

I'm having the same issues....  Its random though.  Sometimes I can play the full game and other times I just crash...
