I find the underage / pedophilic nature of the sexualization in a lot of modern anime disturbing. See: Nowi in Fire Emblem.
"Oh but she's a million-zillion years old for real!" Yeah, right. I found it so hard to look at Nowi that after 2-3 levels I never used her again. I feel like I've seen similar underage-looking girls in most fan service games lately, e.g. Senran Kagura.
I feel like the fan service in general contributes to an anime cliché / nerdy vibe in Japanese games, but I can deal with that if they just keep the pedophilia out of it.
