I have it now for 2 days, and it is a rather nice game, but battling Dooku, Grievous and Windu made me freak out whenever you knock them down to an empty lifebar or almost empty, they seem to find new vigor and come at you more powerful than the whole fight before. Insane.
Anyway, I must say that seeing Anakin wipe out the Jedi as it happens in the game should've been in the movie. It is powerful, what the Jedi say, what Anakin says. That was sorely missing in the movie. Taunting Cin was good as well. When I beat Windu, I thought... neh, bit too easy.
I did find a way to score mucho Masterful kills. In the JediTemple, the section in the hangar, waves of Jedi come at you, and you quickly build up experience, hacking away in short time to Masterful kills. The meter empties than, but if you just continue on doing it, you reap a lot of much needed masterful kills.
I'm now at the point on Mustafar where you battle those Neimodian guards, been there just once so far.
A point I really don't like about it, is when you get clobbered, you really get clobbered. In the duels, it's almost as if your whole controller switches of. Jumping away doesn't work, force-push, nada...
Also, all those combo's, you never know if they work or not.
Ah well, it's a fairly nice game, and it does keep you coming back to further travel down the path, so that's good.
I hope the Obi-Wan fight is good, and that I'm not crap at it. I rarely play these kind of games, I prefer RTS and FPS.
BTW, I didn't have any of the huge sabres in the library and I have the XBox version.
