Monopoly was one of my favourite games when growing up, right after Risk it was probably the second most played game at home. My niece and nephew are now in the age to play monopoly and I will probably gift them the newest version at christmas. Having a monopoly game at casino could be cool, if there are enough players for a full game. For me it'a bit boring to only play with 1 or 2 other people. The large casinos with a high number of regulars could pull it off to get full games. Another good thing about Monopoly is that everybody knows the rules and has played it before. The casino could be the bank and take a small fee for providing the infrastructure to play and then players could buy in for their start money and cash out after the game is done. If casinos add board games to their games it could be nice to add a broader range of games like Settlers of Catan or Risk.
