Besides Asian women just tending to look younger due to facial structure, this is Eve in the 2019 reveal vs the final game:

This game may well follow suit and the design may evolve over time.

She does definitely look young-ish, but I went to University with women 18-22 from Japan or Korea who looked similar.

For me, Krystal from Starfox Adventures definitely deserves a special mention here. There's a reason she's a furry icon after all. The game literally opens with an up-skirt-shot of her riding a flying dinosaur with her legs spread for crying out loud. And back in 2002 on a 480i screen you couldn't make out that she's supposed to be wearing some sort of white underpants - it looked like you could see her pubes lol. Furthermore, she's definitely a contender for "most revealing outfit in a video game". Oh and she's also trapped inside a flying crystal for most of the game, so she's perfectly positioned for you to take a peek. Did I mention her skirt literally disappears for a few frames every time you climb a ladder with her? Not to mention the fact her official character model for her assist trophy in Smash Ultimate has actual private parts modeled (I just googled it to make sure it's true lol and it freaking is).

Not a furry myself, but Rare knew damn well what they were doing in Starfox Adventures.

Indeed! I'm not a furry either, which made it all the more strange back in 2002 haha. That being said, I'm not against sexy characters in video games, at all. I hope she's gonna be reintroduced as a major character at some point.

I can't believe I forgot to put Grace Ashcroft !
