>>28864234I think the reason people have an issue with gen 1 is simply the association with people who dislike the franchise just because of there being new things in it.
That, and the amount more attention it gets re:megas, alola forms, and special Z moves.
Gen 1 games were probably the best they could be expected to be, but outdated. gen 1 pokemon are fine. Gen one -people- are often annoying, but not always. It's important to separate them out.
