I checked it out first with just the standard Wii remote and it was fun enough. It reminded me of the Wii Sports tennis with actual players.
The next 3 I played with the nunchuk and M+. I had no problem with swings registering or anything like that but I did have a problem with moving my player with the nunchuk and swinging with the remote. If I missed a shot it wasn't because of losing sync, it was because I was out of position.
I decided to check things out with just the M+ and I found that it was fun but I missed not having control over where my player moved. I was in much better position most of the time though. Again, I had no problems with missed swings or sync issues.
I am now determined to get used to playing with the nunchuk as it really pulls the whole package together.
And how awesome is it to have a tennis game with McEnroe, Becker, and Borg in it?
I'm definitely feeling this one more than Tiger. That's not to say that Tiger isn't a great game. On the contrary, it's much better than last year. It's just that I have never golfed a day in my life and I used to play tennis when I was younger (much younger

I would definitely highly recommend this game.
