Well, to revive this thread a bit.
I first wanted an experimet a little with Noise algorithms and their use in map generation, and of course, Monogame was quickest to do it.
It seems I went overboard with it.
Basically, map uses multiple OpenSimplex passes to generate terrain, forests, biomes and resources, and by multiplying the input with certain factors, I can control how the map is generated.
Now, the question is, how to progress from here...
