Best Online PSP Game

[s3v3n777]

Ok guys, I'm looking for PSP games which use infrastructure mode to play against (or with) other players. I have Twisted Metals: Hands On and it's pretty fun, but I want to pick up another game with online play. Anyone have any suggestions?

Online console games are kind of meh, but yeah Twisted Metal is probably the best for now.

I think Socom is supposed to be online though.
