One sign to indicate retro collecting is in fact "dying" is the way that everything out there seems to have been already "collected". There is no collecting, if there's nothing left to collect.
I drove an hour out of my way to hit a stop I used to depend on a few years ago just today, and wow, my mind was blown. They had nothing. I actually said out loud and didn't mean to "the stock has definitely shrunk here", and pretty sure they heard me. Everything was picked through, mostly just crap left. I went in thinking "okay, I'm not going to get carried away and spend too much here" to thinking "
isn't there one thing I can buy here?!" There wasn't, I left empty handed. The other nearby stop I used to make near there relocated out of state last fall. Definitely feels like the wells are drying up. Same story elsewhere, other spots I know of that I hit this year, stock didn't change from the last time I was there. Looked like nothing sold, and nothing new.
I feel like I got into this just before everyone wanted to jump onboard all at once. I had a couple of good years where finding anything was reasonable and people at yard sales didn't know "Nintendo is collectable now". Oh well, I'm past the half-way mark to where I want to be anyway. I don't mind buying most the rest of it online really, but it was fun finding things when you took a drive out to look around.
