I picked it up on XBox as well. Overall a pretty nice game. Multiplayer is extremly uninspired, but it does support system link which is nice if you want a Star Wars style shootout. Can't speak to the length of the game yet, but I've been at it a good couple hours and am just getting to the end of Geonosis (I think).
Once you get how the commands for your squad works it's really simple and pretty obvious how to set them up for most encounters.
I also like that the super war droids are tough as hell (at least until you get the anti-armor gun
) and you have to lock on to get your squad to concentrate fire. Very fun.
It feels a little like a cross between Dark Forces and Rainbow 6... with a little more DF than R6.
