The minimap could show which TC is upgrading to imperial in Castle Age.
Oooooh, I need to have a think on that one! Any ideas for how this could be represented? (we of course already use black/white borders on the TC for build/buiolding TC’s)
You can achieve some of this behaviour by clicking technologies that are being researched on the UI as a way to show it. Later we will look into additional minimap info, either in the default mode or in a dedicated view mode.
