Re: Fate point economy question
I'm also a fan of Base Raiders. It's essentially a world that's had Superheroes for some time now, and as such, abandoned lairs and bases are obviously a thing. Your super science base or magical sanctum doesn't disappear when you go missing/get defeated/fly off into space for years at a time.
So a culture of "base raiding" has started to pop up. In the game, you play (at first) mundane characters, who are searching for, and trying to survive, these abandoned bases, in an attempt to gain superpowers. After all, if you can breach the defenses, left behind mutant test subjects, etc., surely there's still some useful technology, artifacts, chemicals, or more?
You essentially have a core gameplay loop of "search for a base, dungeon crawl, potentially gain a power, repeat."
