Essentially what we'd get is a great first year of the cycle and 2 more years of apathy.
Exactly how are we supposed to motivate students to THINK about a challenge from problem to product if they already know the solutions to the challenge? I think a 2-year cycle would be better, and would allow for exactly 1 chance for another design cycle. Not only could teams redeem themselves for past failures, the GDC could redeem themselves for some of the worst rules in the year. Then, they could also add a twist to the game that would enable them to further challenge teams (4th logomotion shape, 4 levels instead of 3, add in
this idea for the minibot, etc).
