Lakeside City: video
Good examples for coherent theming of the overall settlement, adaptive towards its bay location (looks like a harbour city), houses well adapted to the height levels around the bay.
The Land of Arkane: video
Good example for theming, believable structures on the water, good integration of the existing height map. Good bridges and walkways to ensure mobility.
Waterfall City: video
Visually distinct districts, combination of singular large structures with smaller, more repetitive houses. The smaller houses are themed according to district, yet show a level of variability.
Frozen Summit: video
The building material and style of building reflects the environmental conditions. Also, larger structures that are adapted to the changing height.
