I've made a pool on discord recently, what type of biome people would be interested in next, and people overwhelmingly voted for an urban biome. The second map biome voted was a winter theme, so I combined the two and made a winter city layout. The city is less dense than some other urban maps I've made, but it features more varied natural surroundings and different height levels of the terrain, so I think this setup should be interesting to use.
The map set is not perfectly modular, but you can still connect those sheets differently with each other, getting some varied combinations.
