Gabe Newell: "We think there is a fundamental misconception about piracy. Piracy is almost always a service problem and not a pricing problem. If a pirate offers a product anywhere in the world, 24 x 7, purchasable from the convenience of your personal computer, and the legal provider says the product is region-locked, will come to your country 3 months after the US release, and can only be purchased at a brick and mortar store, then the pirate's service is more valuable."
Steam pulled regional pricing from my country not so long ago. You bet your ass sales went way down and people who were buying games because it was easier just went back to pirating them at that point.
Like you expect someone in south America who makes a tenth of what someone in the US makes to pay the same prices (actually more than the same since this country has like 70% tax on "imported" digital services), get real
