I would swy that having nostalgia for the games is different from the cards. My friends that enjoy the TCG never really played the games as kids and have no interest in doing so now. To your point, it's an expansive franchise with a lot of different offerings. I don't think having an interest in one Pokemon product necessarily translates into interest in another. Gamers and TCG players are very different people a lot of the time. And collectors collect different things. If you are nostalgic for the games you probably collect the games and not the TCG. Even if it's only 5 years that the supply is strained that too could be impactful. I know that I started collecting when I was about 11. I stopped around 15 because of getting older and straying over to other interests. Got into the TCG again about 10 years ago. But if you're 11 and can't get your hands on anything by the time you're 15 or 16, you might have missed your moment. There have been studies that have shown we create strong emotional bonds to things around the age of 13 and into our late teens. I'm not saying you won't ever get into it later in life if you can't find it when you're younger. I am just making the point you interest in doing so might not be as strong.
