I saw some the other day B&M, and I believe they were the same price. It may have been $49.99. My guess is it's to compete with the "WiiPlay/Controller" package.
That was actually my favorite part of the game.
At first I bought the game thinking, "It should be fun to play with the roommates drunk." We ended up playing only one or two rounds of the "real game". In comparison, we spent hours upon hours playing the minigames. They're simple but fun...
Making of Video might be cool to watch. Will Wright gives some decent interviews.
But I doubt it'd be worth $30. I might consider it if it was only $10 more.
Ugh. I bought it about a month ago for $20 from Amazon.
As for the game, I kept wanting it to be good, it just never met those expectations. The more I played it, the more its flaws became apparent.
