Now, before I begin this will not be a comparison from the first one. Now that that's out of the way...

User Rating: 8 | Star Wars: The Force Unleashed II WII
Presentation: 4/5
The story in the game is about starkiller coming back to life (although as a clone) and that he is trying to rescue his love Juno Eclipse, now that's all i'm really going to say because I don't do spoilers to much... The story is decent, and the voice actors do a great job at presenting it.
Graphics: 3.5/5
It doesn't push any boundaries on the wii but there are moments where the graphics can look great, there are some really flashy effects on your combos that may even look better than the hd counterparts. And force sight is a pretty nice touch, but the cutscene rendering wasn't really necessary.
Gameplay: 4.5/5
The controls are nearly flawless, I had no problem using force push, lighting, rage, etc. and its really great, you can level up your skills as you slash your enemies down and it works really well, although the boss fights are to easy, and the difficult randomly ranges from easy to hard. But, mostly easy this is pretty fun though.
Sound: 4/5
As I said, the voice actors do a great job and the music is fantastic
Lasting Appeal: 3.5/5
The game is about 8-10 hours long, you can go back unlock some costumes, concept art, cheats, or just power yourself up to maximum, there are 5 difficulty settings ranging from easy,normal,hard,unleashed, and insane (I played on normal since unleashed and insane are locked) and there is a multiplayer mode, but its a shame that mode didn't have wi-fi.
Final Verdict: 8.0 Great
(Actual Score: 7.8)
Star Wars: The Force Unleashed 2 on the wii is a great game, there are a few minor flaws here and there, and the game can be pretty short. But all and all the great controls, solid voice acting, the small bonuses, and the multiplayer make this a great game. Wether, to rent or buy it is up to you though. The force is definitely strong with this one. :D
