Personally I fond the 2d ones nicer, idk why bit pokemon look better in pixel art. That and modern pokemon has so many loading zones.
Tried to play sword abotehr day and damn so many loading zones,
That said I will admit things like signature moves look a lot better in 3d, its just loading times for crossing a bridge is uhhhhh
What I’m tryna say is I prefer the looks of pixel art Pokémon.
The 3D for sure. I love the original Pokemon games, but I think the best part of Pokemon is how awesome and wonderful the world is, and the feeling of exploring it, and that’s better in 3D. Despite their faults, I thought Scarlet and Violet were fantastic
