The single player, well.. prequels are way over rated. But I guess after you give the gods a good thrashing, what else is there that is left?
Multiplayer is somewhat fun, but you still have to deal with the camera zooming way out (making it difficult to see) here and there. You also can't choose which map your going to play on, although just exiting and restarting (a couple button presses) and you can speed through till you find the one you want.
Over all the game does in fact feel like it was rushed and not all too well planned out. It's definitely worth renting if you're a fan of the God of War series, but don't bother with multiplayer unless you actually plan on owning the game (multiplayer requires an actual download code which can be purchased thru the playstation store for $10).
