The lights are on
I just picked this up. Played the first 30 mins of it(Just about 30 mins) and I say it's fun, but every game has it's faults and nasty bugs. So I'd give it a 7.5.
I agree with the nasty bugs, attempting split screen after playing on single is just begging for a crash. Overall, I've had a fun time with the game.
You shouldn't review a game if you haven't even finished it yet. That's more of a first impression.
