Because Argentinians have to pay the "full price" of a North American on each Game Release and we don't have such economy as the United States. Our Salaries are 1/6 of North Americans and a single game cost some of us 1/4 of their total Income. This promotes piracy and left users with no choice whatsoever than to buy games with credit cards at imposible prices. Furthermore, Steam now block games that are brought from Russia (the only country with aceptable prices for us) creating further blocks to our legitimate desire to adquire legit games at fair prices.
