Grand Slam Tennis is a great first title for a new EA Sports franchise. There are some things that can be improved for a next year version, but this package is pretty solid. It really shows how much of a difference Wii MotionPlus makes, and players really need to invest in the unit to get the most of this game. If you miss out on it, you're just getting an expansion of Wii Sports Tennis. The money and time spent on this new playstyle is definitely worth it.
Plently of nice features, a handful of players to choose from, and the great online experience makes Grand Slam Tennis a top offering in terms of Wii sports games. Its the accurate controls and addictive gameplay though, that will keep you engaged in it for a very long time.
