One truly iconic example: Desert Bus. Created by the magicians Penn and Teller in response to Janet Reno's complaints about violent and objectionable computer games, it was intended to be a videogame that contains absolutely nothing that would possibly be considered objectionable, in any manner, to anyone, ever. Desert Bus has, nevertheless, achieved cult status, with fans and detractors alike considering it the one true 'worst game ever made'. The plot of the game? Well...there is none. You are to drive a bus from Tucson, Arizona to Las Vegas, Nevada, on a flat desert road. The trip takes eight hours. Real time. With no way to save the game or pause. Though the road is totally straight the entire way, the bus is designed to pulled to the right constantly, making it impossible to simply 'tape the joystick down' and go for a drink. The bus can't even crash -- there's nothing to crash into. If the bus goes off the road, at any point, the player must wait for the towtruck to arrive from one city or the other, which happens, again, in real time.
