So i got the chance to play SW: TFU on the Wii, and i gotta say i am very impressed.
First off the controls, which is the most important part.
They are damn good, they're responsive and it hasn't registered a wrong direction so far... not even once. Using the force must be the most fun i've had with almost any Wii game. All in all swinging your remote to use the lightsaber feels very natural and fun. Also, the targeting feels easier in this version than the HD ones.
Now for the music, i'm no fan of Star Wars (never watched a movie or something) so i don't know if it's supposed to be good but i didn't like it xD Hearing your lightsaber through the Wii remote is a bit of a letdown because of the very poor sound quality (of the remote speaker) but who cares, you can turn it off. Voice acting is good, but The Apprentice has a terrible voice. And i mean terrible, it just feels wrong.
The graphics are impressive for a Wii game. Explosions all over the place, reflections on the floor, destructible enviroments, lighting effects, and amazing character models (at least for The Apprentice and Vader). Also, when something is behind you but still on-screen it's a little blurry, to show that you're not focused on it which is a nice little addition. Only bad thing is some low-res textures here and there but nothing major. Oh, and the outdoor enviroments (at least the 1st one) suck, while the indoor ones (like the one shown in the IGN developer walkthrough look great.)
Long story short, i am buying it. I'd give it an 8.5/10 and it sure is a must buy for a SW fan and at least a must try for any Wii owner.
Edit: Oh and btw, do NOT buy the DS version. It's awful, laggy framerate, bad graphics, AWFUL controls.
