I had to try this, so here's what I think
The Jedi part isn't too bad, there's more content there than I though there would be, sadly there's no way to catch movement of turning your wrist. The duels are crap though, it's like a terrible mini-game, you start off just blocking (extremely) slow attacks, then you go to a lightsaber clash thing where you line up a thing on the lightsaber and then you can do some type of attack, then if you're successful then you are able to actually do damage until a timer runs out, then you do it all over again and keep repeating until it's over. It's truly crappy.
Besides that, there's some speeder stuff, it's pretty easy to steer, but in some cases it's dark which makes it difficult to see (there's no brightness setting in options).
Also at times you use a gun turret on the spaceship, which aims pretty well, it just fires whenever you get it aimed on an enemy ship.
The other thing is podracing, which you need to make sure you're using the controls correctly and it's pretty fun. That one's worth playing.
Dancing is just dancing, I hate dancing games so it's crap either way to me.
I haven't tried the rancor game.
Anyways, overall I'd give it a 6/10
Shouldn't be $50, more like $40
