I mean it's not an issue and more sound having both look older, Tails redesign has already been considered as the more masculine look instead of curves which allows for more detail without changing him too much, more so matching the other character styles to fit in the game better.
I also don't like the fashion direction a bit. In the sense that the original created the effect of how the characters would behave in the same situation if Sega herself did it. I mean, the characters were very similar in character to the original characters in the Sonic universe. rouge is sexy and mature, she knows this and has used relatively adult content and jokes in sonic x, so it was properly developed in this mod that she likes what is happening around. Amy is a cheerful energetic girl, a cream cultured fragile girl who never parted with her chees, and tails was a boy who did not even think about sex, he is very smart, but still a child who has a slightly childish worldview, even his special attack is not serious . That's why I liked that in this game, tails discovers the topic of sex for the first time, he is forcibly drawn into it and for the first time he learns the peculiarities of perversions in the world. And here it turns out that he is already a man, there is no this effect of knowing sex, there is no such childish naivety, he is already an adult and that is why it upsets me, he loses his originality. In the future, when other male characters are added (knuckles, vector, etc.), then against their background he will be the same adult ordinary character, without the personality of shota
