When you are filtering players, if you filter that you want "Central American players" you get a bunch of Mexicans. FYI Mexico is part of North America not Central America.
i always thought central america was mexico <--> panama? all i can say though is that the demo is meant to be a beta, in other words, if you have a problem with the game then go to the forums http://community.sigames.com and let them know. i can tell you from experience they will take your input on players stats and change them and change any flaws you find in data or programming.
I noticed this too a while ago. I just changed it on the old CD with an editor. North America is always listed as 3 countries: Canada, The US, and Mexico. Almost everyone seemes to forget this 1st grade geography lesson.
