Gnometown Hero
Last Kids on Earth, Kibo and the Age of Wonderbeasts and other cartoons do Gamma World as well as anything the Baby Boomers or Gen X grew up with.Is it? Look, I'm not going to besmirch the game as I've got a lot of fun memories playing it, remind me tell you about Fumbles the mutant scorpion sometime, but I don't know how much it really resonates with the young, hip kids these days.
Gamma World could certainly sustain at least a single adventure/setting book like WotC has put out for other settings in recent years.
