To be more specific, I'm looking for art in a current game where it starts minimal and you can upgrade two or more levels to the final stage.
For example, you start with a hut and you can upgrade it into a town and then city.
Or a small building that upgrades to a skyscraper.
Thanks in advance.
Ginkgopolis is a good example of what I mean.
