living in brazil, these usually are the reasons for piracy. Many games only reach our market several months after the game was released, and with a price most gamers can't afford to pay (prices like a quarter the average salary interns earn).
Personally, i have been avoiding piracy the most, yet distribution still forces me to go pirate. Recently i tried to purchase Civilization Chronicles directly from the US (since no store sells it in brazil), and no US company would deliver it to my country. So, my options are very limited, and priacy is the only one that looks reasonable.
