IDK, nobody is saying Aztec Monks are not readable, so I dunno. I think you can design the units in a way that the silhouette looks the same, but the ‘gear’ is different. When they did the events and I got the Legionary (or the Princess Yodit for Gbeto) installed, is where I started having problems with reading the game.
I’m sure they can keep the silhouette/model the same while bringing in more appropriate skins.
I decided to do another version of this, but with different costumes for villagers from each region (drew them myself). The default villager skins already in the game would go to all the European civilizations.
If they’re going to do this at all, they might as well do it well, not just change the shading on units which could be done by amateur modders with minimal effort. This means regional attire, and appropriate phenotypes. Even so, just added a filter that changes skin/hair tone would be a good intermediate step, and would be incredibly easy.
I think the community has always been ready for it. (I’ve never been aware of anyone saying they didn’t want it, or resisting the idea for anything but logistical reasons).
You may be taking this game a little too seriously.
