It would be cool if we added the ability to play games with other players. Board role-playing games like Mafia or Spy come to my mind. Making money playing favorite games would be great!
I really don't think you can play Mafia or spy on an online casino because there are things that you need to put into considerations
(1) The cost of running a server for that kind of heavy graphics game will be huge for the house, if the Casino is willing to pay big money for running and maintenance, will you be ready to wager a big amount to play.
(2) If the games are high dedicated graphics, will you be ready to pay to subscribe for a large amount of internet bundle, you will likely spend more to play these kinds of games in Casino.
Lets PS5 and Xbox handle this, you can invite your friends over or play multiplayer when connected over the internet.
