I bought it on Saturday in anticipation of bringing it to my friends house to play. Of course, I had to download the "all unlocked" save from wiisave.com before heading over (I do plan on playing through the whole single player). I must say, it's a ton of fun...very addictive and funny. It was a bit awkward doing Bungie Buddies at first, but it's so ridiculous and fun you forget all about it (except maybe the Consolation Poses).
We ended up mostly playing Bomb. We're still a little confused as to how exactly some of the forms work (especially Discard). It's a little frustrating sometimes when you do something but it doesn't work the way you expected. Also, it does seem to be a bit repetative after a while (I wish there were more games). Either way, it's ridiculously silly fun, and a definite must-play.
