I could look for them. But when the only people I meet are from the US with an occasional person from the UK, the logical conclusion is that most players are American. And geographical matchmaking would not be a factor since I only meet people from the forums to raid. Thus, they could come from anywhere. Regardless, at the very least there are MANY US players in this game, and it is a US company. I see no reason why they shouldn't participate in our cultural events.
