Gee, 2007, my graduation year (ignore). OK, by then, the anti-gravity floor would've been made, and all teams would have to build around that.
The field would be like a giant orrery, with a large sphere in the center. In order to score, a team would have to take fake asteroids and attach them to the center sphere. @end_of_match: go into orbit around the center sphere.
Just dreaming. LOL
