I'm thinking about buying a Nintendo Wii but i'm not sure if its a good idea. I had an idea that you need a different controller for each game, for a shooters game you need a gun, for a racing game you need a steering wheel can anyone confirm this. I have a playstation 3 and I'm a big fan of first person shooter games, I read a review that if your into shooting games then the Wii is not for you.
