@ Russell Carroll - Actually, not all Wii U games will be rated M Square Enix is working on DragonQuest X http://www.dqx.jp/ for the Wii U and for the Wii, which will most likely be rated T if it gets released in the US.
@ Ryan Creighton - Even if you were joking, that could actually happen as Pokemon toys and cards are popular. Anyhow, in case of 3rd party, the NFC tech could be used for a Yu-Gi-Oh game if Konami is willing to give it a try.
