I tried out the dancing game for a direct comparison to Wii's and Kinect dance titles, a sports title and a kind of action game titled Move heroes or something.
My interest in Move wasn't that big as in Kinect, because it doesn't seem to deliver more than a more precise Wii experience, without Nintendo games (I'm a N fanboy).
Move seems to be more precise than Wii Motion plus. That's what I got out of the demos. As with Wii and Kinect games though, it depends on how well it's used.
The dancing game is fun, it seems to recognise the movements more precise than even the Kinect dance game, but it was less fun than that, because it only tracks one hand (I don't know if there's a mode that lets you use two bulb controllers, but even then, it's only the hands)
From the sports title, I played table tennis, sword fight, and boccia/boule. In table tennis, the racket movement seems a little more precise than in Wii Sports Resort, just moving it around. But playing was weird, because I did a whole lot of unwanted hits while striking out. Also sometimes I would hit the ball that was just coming over the net while the racket was in front of the table, so it seemed to have a kind of spooky action at a distance. Sword fighting worked great, and that's great because Move should be able to deliver some great hardcore motion fighting games. Boccia was weird again, because throwing wasn't intuitive - the game would often just refuse to let me throw, I think just becuase I wasn't moving quickly enough and the throw would have been very short.
That Heroes title wasn't very good or fun, and movement recognition didn't seem very well. After playing the Zelda Skyward Sword demo, this didn't feel right.
My conclusion: The games I tried didn't deliver anything new, and most controls didn't seem to be well implemented. But from a technical point: Move should be able to deliver cool games with great controls - developers just have to try to make them great.
