2 * Two continents, a rich one and a poor one
3 * They're separated by an ocean, and in the middle of the ocean, there's another, uninhabited continent. It's long & thin, just mountains, nearly impassable, except for a system of mazes underneath.
4 * You are a smuggler, who smuggles drugs from the poor continent to the rich one.
5 * Current mazegen system is used for in the middle continent.
6 * Crafting system for boats. Probability for stuff. Ex: really attempt to build a boat without a guide? x% chance of failure, only y% with a guide.
7 * Plot twist: the two continents are just one continent that extends all the way around the planet. People get progressively poorer/richer as you go around.
8 * Potential difficulty with simulating a *sphere*?
9 * Maybe just make a rectangle where one side overflows to the other, like pacman?
