On a second thought, Otherworld will like every player around the world to patronise them. But in reality, it is just different. This means that the issue of restrictions bothers Otherworld than us because they are into business. So, let's be patient with them as they go about this process.
Each jurisdiction has its own regulation when it comes to gambling. Even though Otherworld wanted the whole population to be their players, they must comply with the policy of each country, or else they will be bombarded with lots of issues and problems from countries that restrict their citizens from gambling. Every business owner does not want to experience that so I do not think they will bent their rules on the restricted country if it has something to do with the government policy.
If they really want that to happen I guess they need to comply on the regulation set by the government on each countries in the world. But we know its not really possible for now especially that we don't know if its really worth it knowing that they are not sure if they would get lots of people to gamble there.
So maybe what's better for now is they need to manage to make their casino became more successful and once they manage to gain good reputation they think about expansion since with this maybe they can attract lots of people to play on their casino.
Anything is possible bud, it is very possible for otherworld to expand into several countries of the world or even all if they want to, the real question we should be asking is if they have the financial capabilities/means and the right connections, because it's one thing to have money and it's another to know people who are in charge and ready to accept the money to give you what you want.
Expansion and growth in reputation can always go together if the casino have the money and resource needed to achieve this, gaining good reputation is all about building a user-friendly casino and ensuring that consumers are ultimately and always satisfied with the casino's services, and always providing constant bonuses as incentive to keep the gamblers coming back and also inviting their friends.
And another important one is marketing, having and running a long term marketing across different platforms and media cost millions in dollars, all this before we begin to talk about buying licenses that gives the casino to operate within a jurisdiction or country.
