Your original demographic has grown up now, GameFreak. It's clear what they want now. It's time for you to grow up too and stop being scared of embracing change.
Plus, you've got fucking Nintendo money, so budget is NO excuse
Original demographic? I don’t know man, I’m almost 40 and the Palworld trailer just looks like a bunch of zoomer shit to me. (Which is fine, of course.)
Legends Arceus or whatever it was called could have been my favorite Pokemon game but they took so many weird decisions and made it a chore instead of fun and as always made it super baby mode and didn't go for any kind of online options. A good 3D Pokemon MMO is possible, but Gamefreak and Nintendo don't seem to have any interest in one ever existing. Also, I'll be honest, I see no reason whatsoever that they limit the Pokemon available and cut old ones, with all the money they have and employees, there's no reason they can't incorporate every single pokemon into newer games and in an MMO setting they could even do certain ones active at certain times or some other way to make them feel exciting to get.
