The big-bottomed craft-me-bang in question is Once Human, which cuts you loose upon an Earth infested with Stardust. A world's worth of Stardust sounds quite enticing, right? Touch of Disney with your wolf-skinning, guvnor? Wrong, Stardust is some kind of horrible endemic lifeform. Consuming water or food contaminated with it will drive you insane. I assume the Stardust plague is also the reason for those towering tentacle bosses you'll meet when not fishing or building a patio.
