Saaaame, it seems falling out of love w/ the Pokemon games despite adoring the concept is pretty common, a lot of my friends share the sentiment...
I am not even that into the other collector stuff like cards (esp with how that hobby has been lately, I have gotten horror stories from my card game pals

) BUT Pokemon did instill in me a love of creature design, so do still enjoy seeing fanart of The Guys and playing fakemon romhacks on my Legally Obtained Gameboy Cartridges

Regarding another thing I used to enjoy, I have been in a struggle for ages now to make drawing not feel so much like work, when it's just a hobby and I want to do it for fun. I think maybe because I see a lot of great artists online, I feel pressure to make my stuff as good as theirs. The obvious advice there is "don't compare yourself to others" but it's easier said than done sometimes... Especially when the "others" in question are like 10 years younger than you LOL
So I end up writing down a lot of the ideas I have in a to-do list, and never drawing them because I don't think I'll do them justice. I still doodle, and draw things on a whim, but with the amount of free time/energy I have (and the amount of competing hobbies too

) I often think of drawing, then talk myself out of it with "well, what's the point if it's not going to be presentable?"
Anyway, I wouldn't say I'm "not into" drawing anymore, or at least that's not how I want to be, but maaaaaan has it been a struggle over the past few years
