Did a simple xml mod to basically introduce cities to more biome types for V1.0
There are 3 types of cities generated in the game. Normal sized Cities, Mega Cities, and Wasteland Cities. I've edited it such that the normal sized cities and mega cities are able to generate in more biome types.
Comparisons as below:
[Original] Normal Sized Cities - spawns in desert, snow biomes only
[Modded] Normal Sized Cities - spawns in forest, desert, snow biomes
[Original] Mega Cities - spawns in wasteland only
[Modded] Mega Cities - spawns in desert, snow, wasteland biomes
I left the wasteland cities to spawn only in the wasteland as per normal.
