I'm further along in the game, probably 5/8 complete, and it's pretty addictive. I was so addicted that I even brought my X360 to work to play, but the 500W voltage converter couldn't handle the X360 and kept overheating and shutting down.

It's still basically hack and slash, but with cool button combos and varied attacks. I've heard you can play the entire game just using force lightning and force push, which might be true, but you can use all kinds of cool powers and moves to make it more interesting.
