nta, but in toys there's arguably a small difference from the side of the sellers, which confuses me. As you say, new 8 and 16 bit games are made, but while they restrict themselves to those styles, they are still new products and most are programmed with the wants of the modern audience in mind. And when games from that decade get rereleased, they cost much less than they used to and often come with extra features. Same goes for movies.
But for toys it's different. There's stuff that fits into those categories (Motu Classics, updated for modern wants, or Funko's Savage Lands, new stuff in the old style), but on the other hand it somehow has become accepted to sell old stuff again, but for the same or an even higher price than before.
Part of the answer is obviously that we're talking about physical vs digital products here, but it also seems like toy companies have decided that asking for a higher price is the smarter decision. I'm curious why that is.
