Surprisingly fun and polished. The sheer amount of possible content combinations (buildings, buffs, biomes, races, etc.) make it extremely repayable. On top of that I haven't seem anything THAT chill and relaxing in a looong time.
The concept of opening glades to both increase your building territory and to discover events and new resources is very innovative and interesting since you never know what you will have to deal with next.
The art is lovely with different races that put their own esthetics on buildings.
Good to play a lot or once in a while.
