"This topic was first brought to my attention when I moved to Sweden one year ago. It seemed that the majority of the top Quake players came from there. Then I started to think... for each game it seems that the top players are concentrated to just a couple of countries per game! Is it because of the lifestyle in that country? Looking at the percentage and number of Internet users in each nation it does seem to have an affect on the skill coming from that country. Having lived in Europe, Asia and New Zealand I can say that the lifestyles in each region are very different."
