It depends on the situation. Most situations a little but not too extreme, but in let's say Superhuman I'd say it would be weird if there wasn't extreme. There are also situations where it can be used in a comedic way, like Little Man, or a combination of both like Corrupted Kingdoms. Some Devs might have already or in the future come up with more ways to utilize it.
what do you define as "deformation"? a physical defect or just a stomach that once was bigger due to prego? either case, a bit of "flap skin" or so no problem, but a thing to be turned on by,not so much
I think the realistic ones are hot but the extreme ones kinda scare me. When I see the extreme ones I feel like I'm watching one of the Aliens movies lol.
I would say no, but if I had to go for it, it would need to be minimal, just enough to know it's happening, instead of so much that you think the woman Ms Incredible
