I'm looking to create a simple, "randomly" generated map for a small game.
The game consists of a top-down view of a world, with land-mass and ocean areas. Think of a simple outline map of the world for example.
The closest thing I can think of that I've seen before was the level-generator for the old SimCity games, or the Civ series, where you can set a preference for single continent versus many islands, etc.
What sort of algorithm would be suitable? The map will need to be moderately zoomable, so I can have a "whole world" view, and also a more zoomed-in local view, but I think I'll sort that out later.
Initially I don't need any concept of heights, just two areas - land and sea, although I might extend it later.
