I have raised this before and would love it if some more people comment and keep this visible so hopefully the devs see this and implement this small feature.
It would be awsome if each player could modify their own units and architecture graphics for each civ so we could have proper independent unit and architecture mods without needing modified datasets. This is purely cosmetic and will not effect gameplay in any way for anyone who doesn’t want to modify their assets and should be very easy to implement.
If the devs are not going to do this, at least please explain once and for all why this is a bad idea and won’t get implemented, cause I honestly can’t think of any reason why it shouldn’t happen, as it’ll make people who want it very happy and won’t impact those who don’t care in the slightest bit.
