Affinity based tiles.

[oldag07]

If cities can change their characteristics depending on the faction's affinity, maybe tiles could also change depending on their affinity. Farms from harmony could be all organic and blue. Terrascapes would also look much different.

Harmony farm sounds a really good idea.

Not my idea, but...
Terrascape
Cyberscape
Xenoscape

Harmony farms could incorporate alien crops indeed. It would fit flavor. As concerns mines and generators... what flavor you suggest and why?

You could change the look of mines or generators to make them feel like the affinity. Supremacy is easy, you can just make everything look orange and robotic. Perhaps for harmony you could see aliens working in the mine/generator? Purity would stay the same.

For farms, Harmony should grow weird alien fruits.
