Get it. R&C is the most fun 3rd person shooter I've ever played (any of them).Damn I should probably try R&C again. I rented it through Gamefly way back when it was released and I liked but it but didn't get very far, and I wanted to try some other games so I switched it out for some other rentals.
I hate that the "cheap", greatest hits-esque games sell at $30. That's way too much.
I haven't played R&C, but I can tell you LBP is a ton of fun. Much more so with other players at the same time, but fun nonetheless single-player
MGS level pack is pretty neat too
LBP can be pretty amazing, but only really really shines as a multiplayer game, imho.
