Ok so here's the basic premise. A games design contest progresses as normal, then...

After the game rankings are in from the judges, a playtest period of 3 months follows.
The winner's game gets played by the runners up, the runners up games get played by the third tier games and they get played by the plebeian games. No one has to playtest the plebs games. Then the second phase of the competition on who does the best AP playtest write up. Then announce grand winners and final rankings.
