This is a bit off topic, but for those who enjoyed Zack and Wiki, you may take interest in this. If anyone is interested in the classic goodness of point and click puzzle-driven adventures, this website has tons and tons of freeware, user-made point and click adventures (all totally legal and whatnot). Obviously, you can't play them on your Wii, but you can on any PC. The graphics are obviously pretty ugly, but you know your guys' motto about graphics and gameplay, right? Some of them are actually quite fantastic, and they're all free, so how can you really complain.
They even have a remake of the classic Maniac Mansion (it was on NES at one time, I believe, as well as PC).
Anyway, I just finished 5 Days a Stranger and really enjoyed it.
So anyone looking to fill the void until Brawl (or any other game), I recommend checking them out, especially if you're a fan of Z&W.
