Overall fun and addictive....
Even though there's alot of replay value and things to collect like differant suites and hidden items, there's a couple things that keep this game from being great. Many times I found myself stuck (i.e. glitch) behind a wall or fence with no way out. My partner had to leave me behind in order to move forward, and eventually I died and re-appeared with my partner. Along with this, we found that on the batmobile level, the game froze up 3 times in a row at the same spot (at the docks) and we had to continue to start the level over. Not all these things may be pressent in every game, but it got us both frustrated and made us quit playing at the time.
The fact that there's no online co-op is a dissappointment, but if you have someone else in the house to play with it's no biggie. Overall I enjoy the game very much....but it's not better than the Starwars Complete Saga.
