Heh, Dokapon Kingdom is my favorite game on Wii. The difficulty is relentless, but I'm not above cheating to knock the computer back a bit. >.>
Sometimes I can convince my friend's to play it with me, but the game's much too long to expect anyone to sit through the entire Quest mode. I'd really like to get a copy of the DS version, even if it's pretty much the same game I'd like to have it in a "to-go" form.
