Bus Of The Desert is a one-page trpg homage to the iconic Desert Bus.
And it's really actually good.
The writing carries it, and has an almost poetic voice at times, but the mechanics are also a pretty solid adaptation of the video game. There's a hard mode (keep two tops spinning for four hours) and a normal mode (roll 2d6 every three minutes for four hours) as well as a scoring system.
Overall, I strongly recommend this as a read, and I think it'd also be perfectly playable as a way to raise money for charity.
