The drive from Tucson, Arizona, to Las Vegas, Nevada, takes approximately eight hours when travelling in a vehicle whose top speed is forty-five miles per hour. In Desert Bus, an unreleased video game from 1995 conceived by the American illusionists and entertainers Penn Jillette and Teller, players must complete that journey in real time. Finishing a single leg of the trip requires considerable stamina and concentration in the face of arch boredom: the vehicle constantly lists to the right, so players cannot take their hands off the virtual wheel; swerving from the road will cause the bus's engine to stall, forcing the player to be towed back to the beginning. The game cannot be paused.
In terms of playability, this is kind of genius.
