I wasn't too blown away. I found the force powers fun, but impractical. I'll buy it, but I won't be rushing to the store.
I liked the combat though, but I found the apprentice weird, his voice was too light and his a little too puggy, it didn't make him look like he had just gone through hardcore training. Though I guess it's because they want to make him out as a lightsider by t he end, though if given the choice I'm going with the darkside ending.
Also I was hoping for something a bit more epic than an AT-ST, I'm sure that's really a mini-boss.
In total, I liked it, had some fun and got to play something new (by Star Wars standards). I'm also going to download it for XBL to see which controls I prefer.
