Have it in my cart, about to pull the trigger, but I'm a little worried about replay value. Online play is a plus, but does anyone know if this game will feature extra modes besides story? For example, Castle Crashers has the arena mode which is a lot of fun, and they're adding the volleyball mini-game to the PSN release. $9 is better than $15, but still not a very good value if I'm only gonna play through the game one time (depending on how long it is).
Edit: F it, I picked it up. If this is a limited time sale or price mistake I can always sell the code if I find out the game is short or not worthwhile. I'll just wait for some reviews before I unlock it. By the way, I'm seeing conflicting reports on whether the game has online co-op, 30ninjas said yes, pretty much everyone else says no, so I'm not really sure.
