I first found it rather easy but when you put the Ai of the Difficulty all of the way up it is rather difficult. I love the arenas and the graphics and I really love how their is so much too unlock.
The thing I dislike is that Polygonman really didn't last that long. I also wish after you beat your rival you could see their reaction and hear more dialouge. I say the game deserves around an 8.0 or 8.5 which is not bad at all. How could that be bad? I can't wait until I start playing online!
