Then I realized it was actually an experiment in string theory and it all made sense.
Of course! Tennis is an okay sport, but what if your legs were distorted objects that moved around you in random undulations and a movement could start in one place and simply appeared somewhere else, as if moving through folded time, like a tesseract. Then we could really learn something, make breakthroughs.
The problem is the theoretical particle physics can escape the xbox and seep into your home. My coffee maker created liquid like toast, my dogs seem to manipulate worm holes appearing in the living room and I haven't found my keys for days.
When I finally made it to my mailbox to return the game I was glad to remember that I still had Kinect Sports if I actually wanted to play something.
tldr; this game is bad, so bad I think its a physics experiment.
