VR is interesting, it's technology that is being developed in past decades, but still many people are unfamiliar with the concept of virtual reality. Gambling and VR is new for many people, and I guess many of us didn't try this yet, to be honest I don't even know where could I try this, and I would have to buy VR equipment... I guess I will try this one day!
Highlighted the parts that would really make VR casino a difficulty at this age. Not to mention that even if they were familiar, a lot of gamblers would probably take a double take if they should buy VR to play in VR casinos or just go to casino instead and spend the money they could've used to buy to possibly win more money in playing. Not that I'm saying all would do that, there are a lot of rich gamblers out there, and buying a VR gear for the sake of a new experience seems quite plausible, but the development of VR isn't at its peak yet. Sure, it may seem interesting at first, but it isn't enough to warrant them to prioritize VR gambling than irl gambling, especially since at their positions, gambling is just a past time as well as a way to socialize with others.
Besides, as I said, they're rich a f and would rather want quality service, VR has some horrid weird-ass controls plus its graphics isn't that all amazing in my perspective, so I'd assume they'd rather go to those big ass casinos that would provide quality service as well as a good environment.
