Browsing Rock, Paper, Shotgun for my gaming news, and I came across a review of Rain World. As is my custom of taking a whisper of detail and spinning it into a horrendous sequence of, “so that means…” how about an apocalypse where when it rains, people die?
In Rain World, you have to hibernate between the rains. You have to gather food as you make your way across the landscape, and when you get the warning signs, you have to get inside a box to protect yourself before the deluge takes you.
As an AW setting, why can’t people live on boats or barges or floating platforms? What effect would intermittent superstorms (mostly just rain, little wind) have on a landscape, your ability to produce food, travel and settlement?
You should watch Roll20’s first Apocalypse World campaign. It’s set in a flooded world.
Both my Gamma World and Apocalypse World campaigns were eroding. Since we live in Houston it wasn’t much of a stretch to struggle for the boats, barges, and scaffolds to persist in a crumbling landscape. Every session a geographic feature or settlement was wiped away.
