It is not impossible to do, if you want to use a decent enough graphics for it. I mean it has been done by some gaming companies before, you go into a real casino, not a real one of course but in game built one, and there are games in there, if I am not wrong one of them was named "the four kings casino" or something like that.
Build it on metaverse, and make the coins the token that rollbit will create, and then use the rollbots for items and such, and you have yourself a metaverse casino. Definitely something that is very logical if you want to do it, especially for a place that is already a casino and can do something like that anytime they want.
Metaverse does not mean you have to create all things perfectly in graphics. Metaverse means you create a world for people to experience in and find themselves there. Graphics is only one of many components of a Metaverse world.
A Metaverse casino, I still can not imagine how it looks like?
Building good quality graphics for the meta needs developers and expert artist and you see web graphics cannot be of that quality to run in browser without any app and in coming time Rollbit might adopt towards new concept and that will be fine and many casinos will be opting to it and you can have real time bets having physical experience with gamblers.
Graphics design is very important that makes game becomes more attractive with gamblers. Another thing is mechanics behind the game. Rollbit does all of such very well and they have creative promotion to keep their current users and attract new ones their platform.
