>>24447168. It's not unappealing, but you can also be manhandled when she is 10ft or 30ft tall, and as a bonus, the other interactions aren't as limited or one-sided. There's nothing meaningful megas interacting with the world beyond "Nothing is built for me, so it is all equally meaningless." I get it, and I'll fap to it, but it starts to feel same-y. Feel repetitive. Everything is too small for her, so it's a binary between feeling afraid to break things, and accepting that she will and going wild. Maybe a transition between the two to spice things up, so three scenarios. Not bad, just gets repetitive.
My sweet spot is the 3m to 10m range. There are limitless numbers of human scale situations to explore, because she isn't too big for everything by an unmanageable amount. There are creative interactions between her, objects in the world, society, her partner(s) or victim(s), that have a lot more to them than just "Haha look how small and meaningless this is to me now!" or "Oh no, I'm so big, but I don't want to destroy anything! (and now I accidentally will)." The actions by a partner are the same kind of repetition: "Oh no, I am stuck in her pubic hair!" or on her nipple, etc. "She doesn't know I'm here, guess I'll (try not to) die!"
A large part of my preference is because I prefer written /size/ erotica over art/morphs/shoops. I admit: the "repetitive" part of mega-and-up doesn't feel quite as repetitive in art. On the flip side, the potential creative world interactions where mini/meso can shine have more space to be explored in writing.
