I had it on but the Wii should be able to handle it so it's better to have it on since it will show if your Wii is faulty faster than if you don't and that's good since the warranty is limited.
Zelda = awesome
Wii Play = Wiimote
Rayman = party game with crazy bunnies
Red Steel = wanted a fps and wanna support exclusive games
Monster 4x4 = got it for free when I bought Red Steel & Rayman
