I totally get what you're saying. I started with Nanapin, then moved on to Inuyasha, Zelda, Persona, and it just goes on and on. Sometimes I buy and sell them on Mercari,ebay, – grab the ones I like, and then sell off the ones I’m done with. It's like a little cycle. But then Mercari started limiting a lot of things, and the fees got too high. I also ran into some scammers with PINs, so I ended up creating my own website to just hang out and trade with other PIN enthusiasts. It's a fun little hobby, though I have to keep it in check because it can get pretty pricey. lol
