Valve makes it even harder for jumpers in the region to capture Steam games at a cheaper price.
Steam's regional price means that the cost of a game often varies from country to country, depending on the cost of living and other factors. It’s still up to the publisher to set a price, but regional prices are largely intended to make buying games fairer for those who would normally have to pay the wazoo. Despite its intent, it has long been used by people who want to deal with a game for a cheaper price than they would pay in their home country.
As he points out SteamDB, the last change means you can only change the country of your Steam account once every three months. It has been a continuous attempt by Valve to repress people who exploit cheaper prices in other countries. Last summer, life became more difficult for VPN users when Steam began requiring a registered form of payment in any country where they tried to buy. Do you want to withdraw Half-Life from Argentina with a US credit card? It can't be done.
It seems an unnecessary addition given how difficult it is to change countries on the fly, but perhaps people were still easily circumventing the system. While it shouldn’t affect most people [I can’t imagine many going up to a different country four times a year], it will be a key for determined bargain hunters.
