The 2D Games always felt way more cohesive, and prettier, to me. I feel a lot of my issues arose from it going 3D with XY.
I do not need the games to look god-tier, and I do not need the games to be 'Souls Hard', but to me, most major aspects of the games feels worse nowadays. I can excuse bad graphics if the game is still fun. I value gameplay more. But to me, the games lately are both too easy, with no non-intrusive options to change it, while also looking so... hm. I thin incohesive is my biggest issue. It just feels like, since SwordShield at least, characters and world and effects and models, do not mesh well. At least not to me.
The scope of their games keeps getting bigger, with open worlds and junk, but it just does not look 'nice' to me. It looks like something is wrong. And since both the graphics, and the gameplay, is pretty bad, to me, it is hard to not be a bit negative, since I DO love Pokémon.
I also do understand why a lot of these issues exists, they are not a gigantic company, and I am not gonna go 'lazy devs' or anything, but the games just feels uncofused.
But that's just me. I dunno.
