So I had an idea for one based on an episode of a kid's show I've been binging lately for the nostalgia trip, its a kinda stupid idea, but I'd like to do it if people were interested:

A most-likely-Free level RP based on the age-old literary concept of Boys Vs. Girls, only in a hilarious Terminator-level of grimdark. The idea is through time travel shenanigans, a young girl in the present has created a future where girls rule the world, and anything "boyish" like action figures, footballs, bb guns, and the like are outlawed. Boys are transformed into girls whenever discovered, and hope is nearly lost. The remaining boys have formed a resistance group to try and fight back using ramshackle technology and junk, like old football pads as armor, or a tin can launching weapon. The idea is pretty ridiculous, and I doubt anyone would take it seriously, but its fun to think about, at least.
