The more we see of Bandai Namco's Family Trainer: Athletic World, the more we admit that, while the graphics are nowhere near what they should be, the game kind of looks like fun. It sounded like the people playing the demo were having a great time, at least! This gameplay video from TGS shows that Bandai has chosen to brazenly ignore Wii Fit and make its own leaning-based game, although it obviously uses a simpler method of reading your body motion.
This mine-car game has (one or) two players lifting a foot off of the mat in order to shift their weight and cause the mine car to turn at the appropriate moment. Jumping is handled by, well, jumping. It kind of looks like the pointer's involved in some way, as well, but we can't figure out how.
