Why are people complaining about the price? Just because they are asking you to pay less money you automatically think it's crap? What the hell is wrong with you people?!
I'm pretty sure people are imagining it will be the same size and quality of R&C: Quest For Booty, which although very fun, was insanely short and didn't really do much for the storyline.
I personally can't wait for this title and plan to pick up Full Frontal Assualt at some point as well (the bad reviews put me off :().
