Games for this fall.

[Jo The Shmo]

I have a PS3 and a PC.
I don't really want anything new for PC, because I am running out of good multiplayer games to play when I have friends over.

I've decided it's down to 3 games:
Dead Rising 2
LBP2
Need For Speed: Hot Pursuit

I never owned DR1, but I used to play it at friends houses all the time, taking turns. Recently, one of my friends just got DR2: Case Zero, and it was very fun to take turns.
Since DR2 will have full co-op, it seems like a very fun game to get.
The problem is it's [i]only[/i] co-op, meaning 2 players at the same time, and a majority of the time we will want to play 4-player games. Plus I'm pretty sure one of my friends is planning on getting it, so I will probably be able to play it nonetheless.
Also although my parents probably won't do/say anything, I'm sure they won't be too happy about the gore factor.

I did own LBP1, and I did play it a lot. I never really got into the level-making, and I didn't even finish the story, but I definitely had enough fun playing through user content with my friends. A bonus is that I can still play it when there are little kids around or something.
The problem is that I didn't get nearly as much playtime on it as I did DR1 or on the older NFS games.
Plus I understand that it has a lot of added features, but honestly, I think just having LBP1 will be good enough.

I know the Need For Speed series has been going extremely downhill lately, but I hear they are trying to make the new one a lot closer to the old ones. I had a LOT of fun playing Hot Pursuit, HS2, and Most Wanted, and I did kinda enjoy Carbon. I loved the police chases and thought they were by far the best part of the game, which is good, because this new one is based around them. I also owned Burnout Paradise, and NFS:HS is supposed to be on the same engine, and I enjoyed the crashes in that game.

I know these are 3 very different games, but if you could help me decide based on my opinions of the past versions, that would be great. So what game should I get?
