Actually American accents are really European accents, and Asian accents, and middleeast accents and ect, ect. considering what most people accredit as American accent only applies to about 7% of the population. Also depending on where in the country you go they sound compleatly different than any other part. People from Georgia sound different than folks from South Carrolina, and they share a common boarder. Just like Countries do..
Don't bother explaining, it's the cool thing to dislike everything American, including our accents apparently.
OP I couldn't disagree more. I personally like the variety in the game, but it's a fictional world. The developers can make the accents however they see fit
