Why did you bloat the Wii with such useless crap? Nyko Gun and Wii Zapper are not needed for anything. Nyko wireless sensor bar is entirely useless since you won't put the bar more than a few feet from the system anyways. The Wii Wheel is entirely useless, and comes packaged with the game for free if you want to buy it. Essentially all the add-ons you have serve no real purpose, and do nothing to enhance any game.
Also, you have the Wired/Wireless abilities backwards. It should saythat the PS3/Wii have wireless and the 360 does not, but it currently is not the way it is set.
