Eh....
So I then played the game on single player because I did not have wifi connected on my wii. The game play was ok, but I was really unimpressed. I felt the frame rate was really horrible and I looked over the first page of reviews and nobody else had this problem. I would have assumed this was maybe a problem with my game, but I noticed it on a friends game on his wii also. The sounds are fantastic and really meshes well with the game play.
I was going to give this game a 5.5 and just accept I am in the minority. However I had a chance to play this game on a friends Wii, and we played online. The game was much better online, getting to play with other people. It was fairly difficult, because most of the guys where going all out killing everyone, and I being the "noob" got punished. That was ok and I can give it some extra points.
Overall just not my game, 7.5 with wifi but it sure seems like you could play some better games then this.
