Sometimes I want to buy some games on Steam, but certain games are not available in my country. Is there any particular reasoning for certain games being unavailable? I get that's not Steam's fault, and it's probably on behalf of the publisher, but I want to purchase for the game.
As I live in Uruguay there's not normally the option to purchase a game in a store, so is not an issue of different publishers for different zones (yes, I could always import the game myself, but then I have to pay an import rate of 60% of the CIF value, which I see as prohibitive).
We also don't have restrictive laws about violence in video games like some countries (such as Australia or Germany). Also, some of the involved games are completely family safe (as Civilization IV a few years ago). I can always get a gift, but that requires trusting or getting trust from some unknown individual (I have done it), and requires some effort. It also could break the Steam user agreement, and that is something I don't want to do.
As a specific example, Grand Theft Auto IV was not available to purchase on Steam in my country, but I am able to purchase Grand Theft Auto: Episodes From Liberty City.
Why are some games unavailable in some regions?
