Demo was dissapointing. It's a pretty bad action game with a fancy effects/license paint job put over it. The combat is just dull and lacks challenge. Even the force powers gimmick gets old quick, because you're basically just throwing things around, except it's not as fun as it was in Psi-Ops or Half Life 2.
The targeting is very innacurate and the camera sucks. It's too zoomed in to see all the cool stuff you're doing, and doesn't react quickly enough to everything going on.
Even worse is the lightsaber stuff isn't nearly as good as Lucasarts' own Jedi Knight games. It should have been similar to those with the new force things added in, and a little more ninja gaiden/DMC style fighting. As it is, it's a bad God of War clone that lets you throw people around. The shallow Quick Time Event at the end of the demo was the punctuation to my increasing "meh" feelings on the game.
Throwing enemies around was fun, the first few times, but it's not going to make a $60 purchase worthwhile. Add that there's no multi or co-op and hopefully the full game has a LOT more depth/challenge or this is going to be quickly limited to the kids table.
I did a more complete write up on the CAG blog, but it got lost just as I was finishing it. I might re-write if I get the patience.. grr.
