So that means 100 people per server because theres no way you could travel zone to zone but have to wait until someone leaves, how annoying would that be? You'll just be on a server with 100 people at a time sooooo....... not an mmo. If 100 people is 100 then that make Joint Operations an mmo because thats 100 people. Maybe COD 4 is an mmo cause theres 64 people per server but you're playing with 100,000 people at the same time who are connected to the same server browser server.
