Be Fruitful! is a text-based life sim about tribes of beastfolk living off the wilds. You play one of them: gather and build, explore, love whoever catches your eye and raise the next generation. Beastfolk treat sex as casually as sharing a meal. Nobody belongs to anybody: there are no couples, no courtship and no jealousy, just tribe mates who get along better or worse, and anyone may ask anyone.

Group sex, orgies and festivals that pull in half the tribe are an ordinary part of life, and pregnancy follows naturally from all of it.
