There are very few RPG settings as bleak as this; Twilight:2000 is the first one to leap to mind. But bleak doesn't mean uninteresting. Reign of Steel is, although derived from the Terminator films, one of the most distinctive game seetings I've ever seen. Humanity fights a last desperate battle against flat-out extermination. The all-powerful computers have divided up the world, and see humanity as little more than a nuisance, at best. This is a great setting for just about any type of game system, particularly as a side trip for dimension-hopping adventurers. The highlights are too numerous to list, but for me, the most intriguing things are: the one "Good Guy" computer on Earth rolling through the western U.S. in a semi-trailer, the "Good Guy" computer on the Moon that has to bide its time, and the horrific computer in Mexico that has scoured the entire region of life, down to microbial level. And, not to mention the standard sterilization of humans by the machines! BRRRRR!! Don't look for hope in this one, kids, just hours and hours of post-apocalyptic fun!
