But seriously, how many people have ever been in Portugal for more than 24 hours? Even if you were accidentally in Portugal for more than 24 hours due to an outage of other countries, you could just log in when other countries came on line the next day.
It's not even a problem. I doubt Portugal even happens to people these days. Anyone posting on a gaming forum has no right to complain because obviously they don't have problems with being in Portugal.
Got $60 for a game? Then obviously you could afford to not live in Portugal, and you should spend your money on better things than games, like not living in Portugal.
To be honest, I doubt Portugal even exists. No way Portugal exists in the 21st century. It's all a storm in a teacup.
