More than 500k for sure.
This is how the leaderboard work. Each playlist and each server have there own leaderboards. Best as I can tell ur ranking is ur average score per game. So it doesn't matter if u have played 1 match or 1000.
So to not count people 2 times i think it's best to look at the solo leaderboards only per server(na, Europe, and Asia)
In North America I'm ranked 235k but Ive been pretty good. Jason says 430k. But I'm not sure how good he has been doing. So I'm not sure how much more people have played on these servers.
I played 1 match in both Europe and Asia so I would show up on the boards. I died as fast as I possibly could to try to see the total players. 225k in Europe and 50k in Asia.
So that's a total of 700k players so far at least.Since there is no trial we know that these people either paid for the game or have multiple accounts. If someone from Europe could play 1 match in the NA servers and die as quickly as possible it would give us much more accurate number for NA.
