This game is among the top 10 sellers. It's been out for days, in multiple countries. A good portion of people can't connect, ever, to the server. But what about the other thousands upon thousands who bought the game?
A lot may be doing the campaign, but there should be far far more doing multiplayer. At the busiest stage i saw 5 game lobbies (some of which would not let me join due to some server error or another).
So...i wonder what gives, whether it's technical problems that some lobbies aren't being seen, or another problem.
Time differences and all that shouldn't matter, there should simply be far far more multiplayer games going on.
