Desert Bus.
If you haven't heard of it, google it. It is THE. MOST. BORING. GAME. EVER. DESIGNED.
In fact, it was designed to be the most boring game ever.
Seriously - it's just driving a bus. Down a straight road. For many HOURS, continuously. Because the bus veers slightly to the right, you can't let go of the controller for long. All you do is drive down that road. And yes, it takes HOURS. Nothing happens to the bus while it's driving. You do not stop at all. There is no scenery, just plain desert sand.
And after you get to your destination, you are awarded with 1 single point. Then you get to drive back in the exact same way for hours to get another point. And then you do the same thing for the third point.
The game has a cap on 99 points, but no one has ever got that far into the game, and, according to those who have looked at the game's code, there is nothing that comes after. No joke, no ending, nothing. There are no movies, no cutscenes, no dialogue - just driving the bus. Back and forth. Forever. And yes, it really does take somehwere between 7 and 8 hours of continuous driving, to get ONE POINT.
It is the worst game ever made.
