Idk, us getting the gibbon, siamang and sifaka really does throw a wrench in that for me.I mean at the end of the day, maybe the lack of monkeys completely stems from difficulty in designing them and nothing with appeal with the players.
There were plenty of reasonably simple monkey species outthere, especially with us having the macaque, capuchin, and proboscis laying around for years. Yet none of those was ever used to make more tailess macaques, squirrel monkey or more langurs
