Per the VGChartz game database for puzzle games, Boom Blox had better 2 week sales than X360 Beautiful Katamari, another in the puzzle genre.
And while Zack & Wiki aren't tearing up the sales charts, that game is now at 360k and didn't start out with much better sales than Boom Blox did. Boom Blox seems like a typical Wii game that doesn't start out strong, but will keep selling and selling, like Z&W is.
Torturing the numbers. Hear them scream.
