>>42895463X/Y was when my enjoyment started going downhill. I started buying and playing Pokemon just for the sake of having and owned and played the newest release, not because it really captured or engrossed me or brought me pleasure anymore.
Su/Mo were my last mainline games. I’ve just moved on to other, better games.
That being said, I still consider myself part of Pokemon’s fanbase — I enjoy it in other ways with new mons that come out, designing regional variants, playing old games or side games, the artwork, keeping up with news, etc.
It’s not that hard to watch a playthrough or just buy a used copy/pirate a future gen if I really feel the urge to play it.
