I’m not sure if this is possible, but after the addition of boats, I’d love to see a body of water world generation option. Cataclysm on the ocean! Drink salt-water, and play Waterworld. Find abandoned sail-boats with undead in the cabins… Maybe a cooler with an undead head in it. I want land to be the minority. Race war against land. Helter Skelter. Then, when the ocean defeats the land, the Manson family comes out of the bottomless pit and takes over again.
What I’m saying is that if it’s feasible, there ought to be land to water ratio selectors. It’d be even cooler to have islands, but that’s hard and complex. Just having huge lakes that are like oceans would be enough. And remember, Charlie was innocent. Tex Watson did it.
