"Any planet is 'Earth' to those who live on it."
Isaac Asimov, Pebble in the Sky
I thought I wanted to set out to make a fantasy adventure game of my own design. I was wrong. I already held Into the Odd and (the tragically lesser known) MoldHammer up as near-perfect designs (the former with a bit more crunch than the latter [which sounds amusingly impossible]). After digging into the Electric Bastionland rules (not to mention already enjoying Mausritter, Maze Rats, and other venerable off-Odd derivative hacks), I realized that there is no fantasy design space I really care to fill. I will 100% always play or run or hack any title from that family of games.
So with few other strong contenders for genre, I turn to science fiction, which I've really always admired reading and exploring far more than fantasy literature and games of all stripes. Isaac Asimov, Robert Heinlein, Jack Vance, Orson Scott Card, and William Gibson took up (and still take up) a great deal of my reading budget, among other similar contemporaries.
