>>38999350I actually have more or less thought for the last few days exactly why this is a bad move even on an objective level, taking into account exactly why pokemon managed to take off compared to other monster catching games. Please excuse the copypasta since it gets tedious to write out every time.
Every franchise can be defined by certain core aspects. Upon altering said core aspects the franchise begins to lose its identity. People are fine more or less with every gimmick or change gamefreak has introduced over the course of series because they generally did not change the core of pokemon.
What is the core of pokemon? I believe that what makes pokemon different from every other monster catching series is the connectivity between games of the series. There are no other monster catching games where you are actually capable of moving a creature from a 2004 game (Ruby/Sapphire) all the way to a game that came out in 2017 (USUM). The fact that this is possible to this very day is a testament to the uniqueness of pokemon mainline titles. Now however every single game starting with SS will be a walled garden, incapable of being penetrated by any pokemon not found within its regional dex. Certain pokemon will remain locked behind in the past until the day gamefreak in their infinite greed decides to allow them to return for another game's pokedex. I have no doubts they will use this as a selling gimmick.
This "policy" is an attack against the very identity of the franchise. This is not just a hiccup, this is not a spinoff, they have gone out of their way to say that this is what pokemon will be from now on. They are devaluing the series that has for the longest time proven to be above any other monster catching game for the features it provides players with. Now with future pokemon games limited to a selection of specific pokemon instead of the entire library, it is vastly inferior to other games of its genre, be it in terms of graphics, animations, or story.
