From the Official Website:
24 HOUR RPG is basically the budding and professional game designer's equivalent of a triathalon- You put your body, mind and spirit through some major punishment in a race against time, in this case to develop a full, working, playable role-playing game within a mere 24 hours with other peers. Like a triathalon, there's no "award" for winning; Rather the award is in itself to participate, test yourself, overcome the challenge at hand at your own pace and skill level, and share in the brief glory with your peers.
