Something i know we as a community would greatly appreciate is having new fauna to match our biomes!!!
Turkey instead of sheep
Lions/Tigers instead of wolves
Graffiti instead of deer
Wild Buffalo instead of boars (now all civs can eat??) Or elk
Etc etc.
Players from top to bottom i believe would welcome the esthetics!
Hello Shneider177, I hope you are well. +1 More variety of fauna and biomes is something that the Community has been asking for for a long time. On the other hand, look here
