It would be nice to see all the early gen pokemon that are too simplistic or that don't fit the more long-running aesthetic of the series as a whole receive redesigns. Not all of them need it, but, for example, the Hitmon pokemon.
People only ride Gen 1 so hard because it was everyones first Pokemon game. No new Pokemon game will match how everyone felt playing Pokemon in the 1990s, for better or for worse.
Except for, you know, kids playing for the first time nowadays.
Pokemon is a children's game. You're playing a children's game yourself so you're no better than them.
Though I started Gen I first myself and I can attain to what TC said. The fallacy that people who dislike the original because they're objectively inferior are younger than you is ridiculous. And you're not better than a child anyways since you're still just playing ingame Pokemon. Unless you play competitive which requires actual brain you're the exact same as a child.
