Why shouldn't they? Isn't it common sense to put what is most important to you in the middle? Im quite sure this dude looks more often at the americas than asia. Same for me, I look at europe more than america or asia.

Send it to the top.
Cut Asia in Half so that you can be in the fucking center of the World Map !
