I’d definitely accept the guineafowl in an animal pack, where there are seven other animals to draw me. But in a scenery pack, where there are precious few slots, I’d feel hard done by almost. Especially with a theme as controversial as a ‘children’s zoo/petting zoo pack’. You need BIG draws, like a goat, rabbit, porcupine, lorikeet, squirrel monkey, tamarin, highland cow, pony, coati etc etc to draw the attention of the public. I don’t think your average person is going to get as excited about a guineafowl, simply because they do not have anything particularly EXCITING. It’s cute, sure, but it would really only work as a Savannah habitat filler species or a farm or bird house filler species.
So sure, in an animal pack it’d be an EXCELLENT choice to bulk out a roster and give us a cute animal. But in a scenery pack, particularly a Children’s Zoo Scenery Pack, it’d feel like a real let down.
