That player vs. player game is a good idea and if it's backgammon, I think it's something. But most of the games that I've seen making this kind of pvp games except poker, they don't get much attention.
This is true where most pvp game sites nowadays doesnt really get that much of attention which causes for them to fail. Lots have tried but do end up the same thing but lets see on how backgammon will pull some interest but op shouldnt hope that much.
In talks of licensure then it will vary on countries jurisdiction because we know that there are known or famous sites now doesnt even have a license but talking about reputation and security then having one would give positive impressions.
I have seen some casinos that did this but it's not really clicking. The gamblers that we have right now don't look to this kind of setup anymore. I think if it will be chess or any common game that's very common, it can click.
You mean play against each other "for or with" btc (instead of by btc?)
In my understanding, both prepositions were what he meant to say.
