I hate to say it, but it's been a week since I've played this game (or any other game, to tell you the truth):
I certainly haven't lost interest in it yet, so I'm not sure why it's been so long since I've fired up the ol' Wii (or PS2 or DS). I guess I'm just not in the mood to play games right now.
Update to the update: I just played the game for a good hour or so. Crisis averted! :)
