There is absolutely no need to play this game AT ALL if you grew up with DPPt or had played the original in the past. This game added absolutely nothing but actually made it worse in terms of difficulty scaling, lack of platinum content and the stupid dex cut... and not like SwSh, but actually only 493 pokemon from the original gen 4 games with no added new pokemon not even Sylveon. Incredibly terrible following pokemon, unavailable gen 4 evolutions until post game, game breaking bugs and glitches, 360 character in a 4 directional world which made it super annoying to move around. The additional pinsir etc, isn't even good anymore. It really surprises me that people just eat this up, it only encourages TPC to keep ripping you off or scamming you, this sht ain't cheap.
Don't blame ILCA, from what I've read it's all TPC who rammed their noses right into the development of this game so it doesn't overshadow Legend's Arceus
