No, not at all. But I grew up playing games in the arcade when pretty much all games were like pac-man, frogger, Donkey-Kong, Q-Bert, Etc. They were all cute characters so I have no pre-conception that cute characters are for kids.
Really I think that mentality come from the PS1/PS2 generation when it became fashionable for Sony and others to paint Nintendo as 'kiddie' and the Playstation as 'mature'.
Frankly I always found anyone who thought that they were more mature because they were playing a game where blood splattered about and more realistic looks was pretty immature. It's still a video game.
Certainly there are kiddie games, but Nintendo generally doesn't make games for kids, nor for adults, they make games for all ages to enjoy, including kids. But typically teenagers are 'too cool' for that and want blood, guts, gore, violence, sex, etc. thinking it's more manly. Hardly, but it's a stage most males go through, most outgrow it, especially when they have kids of their own, some don't.
