Not really got far enough into it to tell.
Only two character slots available. Not seen any restrictions costume wise that annoy me yet, been able to create the toons I wanted with no hassle so far.
Powers seem somewhat limited.
Fire, Ice, Gadgets, Magic, Mental and Nature I think. Was hoping for good old Super Strength.
Apparently you can only do missions to level 30, but again, don't know enough about the game to tell whether thats crap or not.
