Is there like a reason why
JustinP is always ignored
To be clear, what Garcia said didn't really conflict with what I said. Maintaining upwards of 1,000 pokemon is a lot of work no matter how you slice it -- even if you can reuse a lot of work (which it still looks like they are, and Garcia didn't claim otherwise afaik). Both sides seem to take from what they hear to the extremes -- they want to say it either took almost no work or it took an impossible amount of work. Making a game with upwards of 1,000 of anything is going to be a lot of work -- Pokemon games take some smart shortcuts that make it feasible to have so many (making the visuals for attacks modular so you can mix and match a limited set of animations with different particle effects, for example).
My post was mostly debunking the specific claim that they were required to remake models and animations from scratch due to the move from 3DS to Switch because they weren't compatible or whatever. It was a silly claim to begin with, considering the same models/animations were already being used on 3DS, Android and iOS phones (Go), and Switch (Let's Go) -- like I said, models and animations etc are very portable (another big example is Gran Turismo 5's PS2 models).
But I also think this whole "how much work is it" discussion is a bit of a distraction. If they plan on having multiple Pokemon games on Switch, like they usually do, then presumably they'd keep the same style from SwSh and reuse these updated assets. If the removal of the national dex was about how much work it took to update them to Switch quality, it wouldn't need to be a new policy moving forward for every Pokemon game -- it could just be a temporary hiccup starting with SwSh, then each subsequent game adds more until all the pokemon are updated and the national dex gets to come back after a temporary absence while they caught up.
But they've said this is a new policy and have implied that each game will have a limited selection of pokemon -- if it's a new policy moving forward, then presumably the games after SwSh will be missing pokemon that are in SwSh even though the assets are already updated to Switch quality. So unless it's actually not a new policy moving forward and all this drama is over a miscommunication, the main reason for this policy is probably not updating art assets.
(edit: built into this is my impression that they don't plan to permanently, at least for a hardware generation, retire any pokemon -- but that could be a possibility, especially in the far future)
