Ah yes, I had forgotten about RE:UC. I should probably pick the one up one day. Also, knights of the old republic is another great star wars game that didn't invlove space battles, but for the most part I do agree with you on that point.
I'm now almost finished with this game, I've gotten to the ending, but haven't yet beat the boss in the real ending, and I'd give this game an 8 out of 10. Really fun game, but not a lot of depth, and not very long. For the most part the game is just a hack and slash action game where you wade through a ton of enemies, except for when you fight the bosses. The bosses are the true highlight of the game as each one has to be fought in a completely different way, and they each have their own surprises waiting for you. It took me around 15-16 hours to get to the end boss, and I completed every side mission, so it's not that long of a game. They did add a bit of replayability by allowing you to play through the game again on a higher difficulty starting with everything you've collected so far and adding a more powerups and stuff to collect (like concept art). I doubt I will play through again, but at least they tried something.
Also, other then the fact that they both attack with a sword, this game has virtually nothing in common with Zelda TP.
