Steam applied more restrictions to gifts activation and trading. New rules limit the number of countries gifts could be activated in. Gamers located in some parts of Europe and South America (and regions visible below on the screenshot) are discovering that once a gift has been bought from certain countries, it can only be redeemed in the same countries. If you add those games to your library, it would only be playable within the same countries. Users living in Singapore, Russia, Brazil, Mexico, and others are furious on reddit. Here's screenshot of the new restrictions: Here's a quick example, if you buy a game from Russia and send it as a gift, it can only be redeemed in Russia and can only be played in Russia, meaning that if the user were to travel to If you're thinking of traveling to another country and playing your Steam games there forget it.

Some unfortunate users of Steam living in Japan have been the first to be introduced to a very nasty new feature of Steam. Basically, games that are not released in your region apparently will no longer EVER be playable over Steam in affected regions. Thus if for example, you purchase DA:O from the US then move to Japan, you will no longer be able to play your purchased game. If you ask someone to gift the game to you from the US, you will not be able to play your gift. Details can be found here: http://forums.steampowered.com/forums/showthread.php?t=1012091 So be aware, Valve now enforce access to your games based on your current IP and no longer apply restrictions for Steam store bought games at the point of purchase only. Expect this feature to be expanded upon in the near future to affect more regions and more games. News thanks to DAO_Japan. You can discuss this issue here.
