It's worth having in your games collection.
I like this. It's typical Nintendo with colourful graphics and simple yet addictive game play. You will always come back to this for a quick blast or when friends and family visit. The wii-motion does make a difference although I'm not sure all the games really needed it. I'm sure the wakeboarding and archary control could be done without motion+ and the controls for flying the plan are the same as in EA's playground game which has no +. That said you can see the difference in the golf, tenpin, and table tennis, and definately in the frisbee and sword games. Yes it's not cheep as you will need two motions from the start to get the best from it, but I feel it's worth it as the + can be used with other games.
