Forgive me if I am misunderstanding here… but are you comparing GW against virtual?
There has been a lot of misinformation in the past regarding this. Make no mistake that Virtual (and all skins), Prism (and all skins) and all GW group casinos are the same entity and are all related. They are put under different affiliate groups to try to seperate them. The ownership and affiliate group had tried to mask that fact in the past but it is too obvious and has been proven.
If this was already common knowledge then excuse the post please.
