Jonathan Cullen, GOONL!NE: "How much of a difference would the game have made without WMP? A lot, but for the wrong reasons, and for that we would had to have taken a couple of points off the final score. However that doesn't need to be done as WMP and Grand Slam Tennis work well together in unison.
Without WMP, take two points off the overall score. However, we suggest getting the bundle as EA Sports Grand Slam Tennis shows that WiiMotionPlus works, and for the better as far as we're concerned. This is what the Wii should be like from now on."
