Killzone 2!

Well, this is a PS3 forum, so you're going to get a lot of Resistance 2 supporters. If you post the same topic in the 360 forum you'll get everybody saying Halo 3.

So, that said, go with R2. :)

Twisted Metal, Syphon Filter.

Buy the game anyways. It's long and deep as hell.

Burnout Paradise.

I haven't tried it, but it doesn't do the disc any favours. Just continue to press the PS button then quit game. After that I take the disc out.

Exactly.

Killzone 2 it is. Thanks all. I'll be buying all of these eventually, just needed to pick which one first.

Can only afford one. Which should it be?

Killzone 2, Bioshock, or Dead Space?

How many hours to beat this game would you guys say?

God of War.

Both are great games and I say get both eventually anyway, but I think you'll love your PSP even more playing GoW: CoO on it. The game may only be about 6-7 hours but I personally have played through it three or four times, it's that good.
