Cyberpunk 2020 is an underappreciated masterpiece. I ran the game for many years as my #1 preference. I wrote articles for INTERFACE magazine in high school and ran CP2020 for R. Talsorian at GenCon. I love that game so much.
Cyberpunk 2020 had automatic failures on 1, with a high chance to botch, as a very deliberate game mechanism that contributed to lethality and danger! The mechanic meant that no matter how good your 'punk was, he could always fuck up. As a result, as a matter of statistics, every mission would eventually go catastrophically wrong. But the bad guys could also colossally botch, too. And that is what made Cyberpunk 2020 so, so, so, so much fun.
