I put in Wii Play last night and the thing wouldn't read. I took it out and it was clean and scratch free. Put it under the sink with some dish soap, and couldn't find a mark on it. Not a big deal but it's my buddies game. Now I guess I get to pick up another Wiimote. He tried it on his Wii and he gets the same thing. Wonder if Nintendo support covers this? I think I'll call tonight.
