It's nothing like Mass Effect, there are no RPG qualities unless you count the level up system which is just a way to get you to keep playing. Anyway, it took me maybe 8 (and that's a very generous guess) hours to beat. There are two endings, though, depending on ONE choice you make. Fighting with a lightsaber feels clunky and unresponsive and targeting is a bitch (wait till you get to the Star Destroyer boss...jeez). It's worth the eight bucks for a rent, but that's about it unless you're die hard into Star Wars and totally unwilling to read the book that came out that's based on the game.
I had fun with it, but have no desire to ever play it again.
