In the case of Melco Resorts, the company is strategically using the popularity of the series to promote tourism and gambling in Thailand. The setting in a luxury resort will inspire many viewers to visit the country and experience the excitement of the casinos portrayed in this production... in my opinion, a clever marketing approach.
I mean. As long as it is nothing illegal, why would this be a problem? Gambling can be a problem if done irresponsibly and at least in theory should be strictly for entertainment and not for becoming a billionaire over night. Sure, getting richer over night is a possibility but is it ever a guarantee?
I do not understand why one Casino may be more exciting than another for a gambler. I have seen a few Casinos and they all offer the same feeling overall. Maybe one of them has newer machines or more games, but other than that they are not much different. Or, did I miss out on details?
