I used to own a game called "Run For the Money" for the Atari 8bit / C64. It was one disk that had Atari 8bit computers version on one side and the C64 on the other. I bought it from a stand in a video game store when I was a kid. It was one of those clear plastic cases, the size of a disk. There was a cover, manual and disk inside...not much at all. I remember getting it cheap, but it was an awesome game.
The game was made by Scarborough Systems and Tom Snyder. I am not sure if it was only released in Canada, as that is where I bought it. I have the ROM if anyone is looking for it. I didn't notice it in the Rarity lists for either system.
