My room mate got it a few months back. We both knew it was a big deal so I decided to watch him play it. He picks up his 3rd party controller and boots up the game. In less than a minute the game asks him to brush his teeth by shaking the controller from side to side. His shitty controller has no motion censor, so he essentially lost the game before it really started. That is my only experience, but I remember hearing amazing things from review sites. I'm not sure how it would be a platform for a tickling game, as the most advance parts of the game were the story telling and branching paths and decisions. It's not so much a technological achievement as it is the result of a lot of additional time and effort. The game was more successful because it was well written, which I think you will find in The Tower of Gargalis (sp?) and The Labyrinth of Laughter.
