Have tried VR gambling but it was in game currency and not real money. It was alright, didn't feel like it was groundbreaking and there's still a couple of years before it gets mainstream attention. I love to play poker and would like to see peoples reactions and tells while playing online and I consider that a downside of Online poker. Online casinos will start incorporating VR tech before it even starts hurting their business. I don't think that would be much of a problem.
