I doubt that casinos in the Metaverse will attract gamblers on an ongoing basis, the effect of novelty will pass very quickly, and I don't see any point in playing in the Metaverse. I think this is a mixture of pleasures. If I want an atmosphere of celebration and thrills, then I go to a real casino, if I want relaxed gambling, then I play on the computer, but I don’t know why I would go to play in the Metaverse.
I think novelty is the most important here... what Metaverse actually has to offer!? Old games in a new way, or there will be new games in a new way as well?! What is that special in Metaverse that should make me think about buying equipment so I can gamble there? From what I saw until now almost nothing! But I guess this is only the beginning of Metaverse and years will pass before they come up with something concrete and really interesting!
I agree with you, I just don't see the options that any Metaverse can offer now. Maybe in a few years, when technical development will make it possible to transmit at a distance not only the image (which modern monitors do superbly with), but also, say, sensations or smells, then it will begin to acquire its uniqueness and relevance.
