I’ve got in my mind an idea for a campaign setting. The premise would be to take the tropes of Vietnam movies such as Platoon, Full Metal Jacket, and Apocalypse Now.
The world is roughly split between two superpowers, a totalitarian dictatorship and a corrupt kleptocracy. The adventure site is a small island in the ocean, about 1/4 of the way to the former empire. The conflict is a proxy war fought between the two empires for control of the island, since it has both strategic and economic value.
What do you think, sirs? A little fantasy Vietnam?
