Steam has updated their purchase and pricing restriction in wake of continued abuse from users exploiting regional price-differences via VPN. You may have read about this recently following the availability of PS4-exclusive Horizon: Zero Dawn on the PC platform, with the release being priced differently by the publisher according to the purchase region of its respective users. However, one way users found to circumvent these restrictions and purchase games at a lower price was to use a VPN service and appear as if they were connecting from one of the lower-priced regions. This prompted a price-hike for Horizon: Zero Dawn in those exploited regions - sometimes by as much as 389%. Such was the case for Argentina, where the game, which was originally being sold for ARS$539,99 ($7,47) got its price hiked to ARS$2100 ($29,06). The game was being sold in US-based stores for $39.

Now, Steam is forcing currencies used on the purchase to match those of the country where the purchase is (apparently) being made. This means you can't pay in dollars a game that is priced in Argentinian pesos or any other currency. This move by Steam aims to keep pricing fair according to users' and countries' purchasing power, and aims to protect users with lower purchasing power from price-hikes derived from the exploitation of regional pricing. An Argentinian user, where the country's minimum wage is set at $233,55, now is protected from users with higher purchasing power being responsible for game price hikes that mean it costs them 10% of their minimum wage to get a single game from the Steam store. You can replace Argentina with any other country that saw its regional pricing being abused via VPN-hidden users who wanted to take advantage of the price difference. I can hear some Game of Thrones bells ringing in the distance.
