Topic: What Should I get off of the Playstation Network?

Okay, so I got a $20 PSN card for christmas but I don't know what to get. The only games I have are Black Ops and Uncharted 2. I would usually just buy some add-ons but unfortunately, none of those games have any add-ons except for Uncharted 2 but I don't play the multiplayer. So I don't really know what to get. I'm usually into FPS and action/adventure games. I was thinking maybe Castle Crashers. Are there any games you would recommend if so how much would it be? Thanks

Wipeout HD, unless you hate Racing games,

Final Fantasy 7

Actually, scratch what I said before, this and Castle Crashers should do nicely.

Scott Pilgrim VS. The World is a lot of fun too.

There is a thread for PSN recommendations here. Please feel free to revive it.
