Centro's getting his shit DMCA'd by NoA so there's a chance some the stuff that was previously posted (I have a feeling that it's more to do with him reporting on the new Nintendo console's specs) was legit.
I think the reasons why GF hasn't been putting out bangers lately is because they still haven't gotten over the growing pains of switching from 2D games to 3D games and poor management of its developers, I remember reading something that said GF was prioritizing original projects over Pokémon-related projects.
That said I think the issues with SV had more to do with the pandemic (I can feel you groaning and eye-rolling from here) and it forcing several developers to move to a “work from home” environment, I know the Smash Bros. Dev team was forced to do that during the development of its second set of DLC characters and it’s part of the reason why Steve is busted.
Eh, I take issue to the “three quests” thing, while it is true you’re allowed to do it in any order the levels of each area’s Pokémon still follow a very clear order.
