Massive load times, slow as snail turds, a world that looks cool but not too useful because of the trophy system, and way too much stuff that tries to substitute how gamers communicate normally.
EDIT: The rewards system was fair, but normally when I just turn on my PS3, I don't want to wait like 2-3 mins for this thing to load up, these aren't the Mid 90's no more when load times were the norm.
Failure is an understatement. When I clicked on this thing by accident, I'd be so annoyed by how long it takes to load back.
But that's just MHO.
