City management is not fun for me. It is brainless and repetitive. There is no large variety of improvements. Most of the improvements are similar. They just give you more resources: production, growth, research, mana, etc. Also there are duplicates that give you the same resource. I would like more interesting improvements. Here are examples of interesting improvements:

- allows to train creatures. More such improvements, please, especially in early-mid game. Recruiting ogres and trolls is needed in early game, not in mid game. Knights of Asok should be shifted to earlier stage too. Also expensive improvements can be added that allow to recruit Troll Warriors and Bone Ogres.

- allows to move without penalty in Forests/Swamps/Hills/Rivers in a large radius around the city.

- gives defence bonus to all units in a large radius around the city.

- allows to deliver items from shop to sovereign/champion and vice versa.

- allows to teleport between cities.
