I actually like Peach's inclusion, even though I have a lot of problems with how her actual route goes. Peach's design is cute (stayed with her original outfit until I got her awakened outfit... lol) and I feel like it would be a waste of resources, time, and money to completely remove her. However, I was hoping there'd be a real bimbofication scenario with her, especially since it hinted that she becomes ditzy at times, but she ends up acting just like an amalgamation of all the corrupted girls before her with little character conflict about Vowser. I like her heart-to-heart with Eros in the bath as well and I think her dialogue there was well-written, but him bringing up the fact their customers had "expectations" of her felt more like coercion than trying to relate to her as a princess of a kingdom. She basically folds under zero pressure.
