@Terasophe Sword/Shield's legacy will be that it was a necessary step towards non-linear open-world Pokémon games, and that's about it. The Dynamax/Gigantamax gimmick sucks balls (even if some of the designs look cool), the continuation of allowing you to swap out party Pokémon with a newly caught Pokémon from Sun/Moon is good, but mostly everything else is just pointless or it makes it too easy (like every Pokémon getting XP regardless of if they're used, even if you catch the Pokémon rather than defeating it).
I wouldn't say I'm all about grinding, but there's literally zero investment in your Pokémon I feel, because you can raise them so easily now. It's like eh fuck it, use whoever, throw them in the box and use something else, who gives a fuck.
