Didn’t have space to clarify this, but I did some cursory research. Most things I came across were aimed at one specific species, whereas I would like more customizability. Technically, GURPS falls under the criteria of what I am looking for, since you can make literally any character that you can think of, which would by definition include all anthros.

I should specify that the reason I am asking here is that I feel a drive to make a homebrew rpg, but if there’s a pre-existing rpg that fills the niche of “game with rules that make your fursona more than just flavor” I would rather just promote that instead of pouring my heart and soul into a knockoff. I’d rather have my work described as “the bastard child of 20 bad wattpad fanfics” instead of “We Have Albedo: the RPG at Home”.
