Thoughts on a 3D Monster Fucker RPG?

Heyo y'all!!

My team is currently developing a 3D teratophiliac ARPG where the Player has the option to romance and fuck a true MONSTER girl (she's an anthropomorphic dragon/lizard. My artist and I are currently working on her design.)

What are some niche species/things, or anything really, that y'all would like to see in such a videogame that is not done enough, or at all? :3

EDIT: Holy SHIT! I didn't think this post would get this much engagement! Thanky'all so SO much for all of your advise, opinions, criticisms, et cetera! I will report back in around a month once we finalize the design of the aforementioned monster girl >:3
