Beyond technological throughout constraints, I just genuinely don’t want the real life commodificaiton of in-game resources.
I don’t want a market existing around selling my virtual jacket in game, I don’t want loan-terms from fake in-game banks backed by a real-vslur commodity determining the investment in my guild, I don’t want to think about the macroeconomic impact of an expansion releasing and how that affects the value of my character.
If a crypto-game actually delivered on the above I bet it would have a playerbase, but they’re overwhelmingly crowd-funding/vc-funding cash grabs whose additional utility is usually less than that of the steam marketplace.
I recognize I’m someone who will never want to play a game that couples its virtual economy to the real-economy (and I think the overwhelming majority of players feel the same way).
