I fully agree. Visage was truly one of a kind business and it really encapsulated the Vegas experience. It always felt like going to another city for a mini holiday and there was so much more you could do than just play poker. Also, the fact that the Visage Casino opened quite rarely, it added to the allure of going to Visage and made it stand out from other businesses. Nowadays casinos in Venturas are opened every night, and I believe it will eventually lose the exclusiveness of going to Venturas.
I also find it a bit disappointing that many enterprises/groups/holdings have vast number of completely unrrelated businesses owned by a single person. Like why does John_Doe own a trucking company, a bar, and a casino? What do these business even have in common? It just shows that you don't quite know what you're actually trying to roleplay. It makes much more sense to target a specific niche, and start building companies that benefit off of each other. For example, if someone runs a news agency, it would make much more sense for them to also run an advertising agency, not a trucking company.
