The Game Earth is a world where a game is big entertainment.
The government on this Earth banned all sporting events ten years ago when the country was on the verge of a civil war. The people wanted to be entertained though, so they started up The Game—a bloody sport held in a walled-off portion of San Francisco where a few dozen teams of players race each other through five levels of tricks, traps and mayhem trying to reach a goal set up near the beach. The first team to reach the goal is the winner and they, or their next of kin, receive $5 million.
A common expression of this world is "See you at the beach." which means "Good luck."
