Valve Really Doesn't Want You Using VPNs To Get Cheaper Games - Kotaku
So a Steam user being disadvantaged by local pricing—or just trying to get a cheaper game, let’s be honest—might try and get a better deal by switching their account to a different country and tricking the storefront into letting them buy their games there.I’m going to guess that the restrictions based on how often you can change it are to stop people in, say, the US moving their account to a different country to buy then moving it straight back to play (as opposed to simply leaving it in the cheaper country for good) because using a VPN can suck if you’re playing multiplayer.This move comes a year after Valve first tried closing this pricing loophole, when they made buying things from different regions harder by forcing users to use a local payment method (so you couldn’t use an American credit card to buy a game in Poland, for example).
