As far as examples of games that really are good with motion controls, obviously there is Wii Sports. Poo-poo it all you want, but the bowling is really fun and most people find a few others in the set that they really like. After playing Wii Sports, a bowling game where you press a button a bunch of times or roll a trackball or flick an analog stick isn't even remotely as fun.
Excitebots is awesome and wouldn't be the same at all with an analog stick. How about Boom Blox? I'm sure there are others (I don't have that many games yet). Now with Wii MotionPlus we've got Tiger Woods 10, which I do have, and it is *fantastic* and is way better then traditional controls golf games. It's looking like their tennis game isn't so successful, though, maybe not successful at all. Perhaps they'll get tennis right for '11? Mind you, I have not played GST myself. A good motion controlled tennis game will be awesome... once we get it.
I'm also looking forward to a good Wii MotionPlus baseball game - batting with Wii MotionPlus will rock. Swing the

ing bat for cripes sake! What's not to like? Only if the particularly implementation of the motion controls sucked, which is always possible, would it suck, but given Tiger Woods 10, I don't think there's any reason to believe that we won't get some good ones eventually. Hopefully soon.
A key thing to note is that while some developers seem unable to imagine a Wii game without motion controls and thus wrongly develop their games only with motion controls or use them in odd ways, there's others that do get it. Take Lego Star Wars Complete Saga. It does offer motion control as a (fairly useless) option to swing your light saber, but really you can, and should, play the game with remote and nunchuck, not using motion control, and it plays just as great as on any other system. My point here is that the developers understood that motion controls would not add anything to the game other then as something to try once or twice, and they kept it designed as a traditional controls game - Wii motion controls did not kill the radio star. There is no reason to get your panties in a bunch, folks.
