Since the early access started today for Xbox and PC you can see how many players now online.
Wow, more than 10,000 on PC alone?!
Despite the maximum limit of 10 hours for EA acess trial games, which means that many have burned through their hours and can't play right now even if they wanted to.
When I played it right after it was available for download there was only one server which was full. And you couldn't try any of the new 3-map campaigns because there weren't any players (What's the new mode called, Operation? Which sounds amazing).
I have tried to save my hours, and have a few left.
