In the current system of criteria to join a nation, a town needs to be at least 12,000 blocks away from the capital in order to be invited. Despite functioning as a form of containment of random and unmeasured expansion, the configuration ends up making intercontinental expansion projects impossible in most regions. Europe and Africa, because they are central continents, have a position of disproportionate advantage for expansion, which did not need to exist, given that the objective is for all continents to have the same opportunities.

In terms of realism, the rule makes geopolitical simulation limited. In real life, there are no artificial distance limitations. As an example, if by chance someone wanted to form the British Empire with the real proportions, it would be impossible, as UK would not be able to add Australia in the same nation because of this rule. The East Indies of the Netherlands could not exist, because Indonesia is located very far from Amsterdam. Is this rule really needful?

In the end, the rule creates problems more than it solves them. It discourages investment in regions that are not yours, which does not exist in the real geopolitical interests.
