I also doubt with the arcade games like street fighter, Tekken even though this is one of the best arcade games in history, still people are not playing this anymore because of the technology grows a lot and this is why its hard to find a crypto based site that offers this options.
Those classic games are being played right now but the gambling market for them isn't that big.
It doesn't matter whether more or fewer people will play those games or not since if it's about gambling, the viewers will only do betting for it.
Actually, it's not with the technology. I'm sure if the pandemic didn't hit the world, these games will continue to have a much bigger market while they are progressing. I've already watched some of the videos of those events,
e.g Tekken, prior pandemic and they have a large audience on the venue.
