The motion plus definitely makes the games more fun - I really enjoyed the sword fighting in Wii Resort.

That said, there is one serious issue. When I first fired up WII Resort, I thought it was interesting they kept harping on how to recalibrate the motion plus. Eveytime a game starts. Everytime you move to a new level. If it doesn't feel right recalibrate.

Well the reason for that becomes evident if you play any of the 'intenser' games, ala sword fighting. The controller quickly becomes uncalibrated. This is expecially bad in the horde sword fight levels - it simply starts getting out of sync after 5-10 enemies. I have to recalibrate it every 3-5 minutes.

And before anyone says 'hardware issue' I purchased two of them. I have two remotes. Every combination exhibits this issue - it's highly unlikely both of my motion pluses have a failure.

This is a pretty glaring problem in an otherwise very cool addon - and honestly is extemely disappointing to me as the sword fighting possiblites is where I was most interested in it. I sure hope it's something that can be addressed in the future via a software patch, but I have my doubts.
