Some great roleplaying games have been produced over the years. Call of Cthulhu. Ghostbusters. Paranoia. So many amazing ideas remain untapped, however; so many amazing worlds remain unexplored. How, we ask ourselves, could the industry have proceeded so far without pursuing this concept? How could the industry have proceeded so far without building a game around that world? Do the writers simply consider the concept out of their league? Do the publishers consider the rights to the property too difficult to obtain? Although we're likely to have different opinions about exactly which game should have been developed, I'm confident that we can agree on one thing: There is a game that should have been made but for some reason wasn't.
My question to you today, therefore, is this: What roleplaying game hasn't yet been created that should have been created a long time ago?
