TBH, I hate Gen 1 based on the storyline based on what I've played way back Fire Red: too harsh, too violent, having some sort of "bullying" because of Blue, which I hate. Gen 1 also introduces gambling via Game Corner which is not good for younger players.
If the Kanto thing was revealed: I was really hope for
Where do we get the livestream of that TV show?
- Expanded Pokedex
- No Pokedex-related story like getting a VS Seeker requires X Pokemon.
- Day/Night cycle so that wild Pokémon varies everytime.
- An evil team focuses on a Legendary Pokemon.
- Retains the best features of Pokémon throughout the years.
I think it's about time we get a rival who's actually, you know, a rival. I'm getting tired of the rival just being a friend who is basically your personal cheerleader. Also, Blue didn't really bully your character, he was just a cocky little shit. Silver was actually abusive, however. But that was a really interesting concept
Additionally, the raw realism of Team Rocket being a criminal organization is far more entertaining than the ridiculous, cartoonist rule the world plots of the past 5 generations' villainous organizations, imo. Some of the concepts from gen 1 and 2 would actually seem original and refreshing after 5 generations of the same thing regarding rivals and villains (although SM at least mixed things up by having Team Skull be a front for the real villian. Same outcome, however).
Just my opinion, though.
