I've just been given a Wii as a freebie, and was wondering whether there are any useful kanji games for it...

Anyone used either of these?

漢検Wii 漢字王決定戦 (Rocket)
250万人の漢検Wiiでとことん漢字脳 (IE Institute)

I'm guess the Rocket software might be better, given their DS offerings, but reviews seem to be a bit thin on the ground.

IE institute also makes DS kanken software that is (in my opinion) better.
