Well. The mechanics are solid, and it looks and sounds like StarWars. I think the biggest thing is the single player mode needs work. In every battle, it seems that nothing ever matters becasue every fight devolves into a deathmatch, even if your objective is something simple like kill the fambas that are generating the Gungan's shields. The fambas are nearly invincible, so it ultimately becomes a mission of slaughtering the gungans who leave the shield like morons. If they grouped together inside the shield, there is no way you could win.
Also, there arent enough weapon variations. Every character gets just two weapons and can't trade out. And your allies are always incredibly stupid. You cant even take an AT-AT down with a cable unless you have two semi-intellignet humans playing, because the CPU won't fire the cable, or fly in circles around the legs.
Something that would help tremendously is splitscreen multiplayer. I didn't even realize that there was none. In fact, I would've rented MK Deception if I knew it was only systemlink or live.
Over all, I give it a Seven/Ten, and if you can play online, up the score to an Eight.
