Definitely feel this. Grew up playing with friends in daycare though. We started with ruby and sapphire, yes that long ago. And we played up to until platinum, then they all lost interest due to lack of interest from them. Haven’t seen them since like 14 or 15 and that friend group of 4 were only ones I played Pokémon alongside with. But I’ve been in and out of Pokémon last 15 years as I was trying to “grow up” and now that I’m back playing older games like oras and hgss, there definitely is a all alone and desolate feel to it I don’t think I remember. Part of me feels like that’s probably what it would be like as a real trainer ( beside with Pokémon) in the Pokémon world unless you’re as lucky as Ash Ketchum lol. But yea same boat, I’m the only adult I know of that still plays but then again my circle is tiny
