The biomes tend to look a bit basic at the moment, especially when compared to handcrafted scenario maps.
The problem is the lack of fine grained options to influence the random map creation.
Therefore, it would be helpful to give the biome.json the ability to define more stuff (e.g. resource availability) and then let the map.js script decide if it want'.
Goal -> make the random maps more diverse, more realistic and more fun to play
As suggested by @smiley this also adds a way to make biomes more easily extensible (i.e. inheritance)
