bansama: So for regions where you don't think you're going to get enough returns to justify full local market penetration, just sell your items via the Internet. Those who are interested in your product will tend to find it (especially when it's a game) with little need for advertising costs.
But the globality (is that even a word?) of the internet is actually a part of the problem. The reason for regional pricing (as opposed to simply regional availability) is that every company wants to sell its products for exactly as much as people are willing to pay for it, in order to maximise profits. However, that price is not the same from region to region. In some countries, the average income is much lower than in others. This is usually reflected in local store prices, and noone complains too much about it, because you can't see the price tags in stores in other countries when you're standing in one of your local stores. Also, there are other local factors involved, such as the lower cost of labor leading to companies being able to sell their products cheaper there. And of course, when you do go abroad, and see the cheaper prices in their stores, you can buy stuff from them at that price.
However, when we look at digital distribution, the cost of selling to one country is exactly the same as the cost of selling to another, so there's an argument out the window. What's left is the price the local market can bear. This is still not fixed, and so regional pricing schemes are used. But now you're on the internet, and it's very easy to compare prices across borders. So now everyone can see that "those lucky bastards are paying only 50% of what we are!" You can effectively walk into a foreign store and look at the prices,
but you are not allowed to buy anything.
