How will you choose who goes into each of the categories? In all honesty I think the multiplayer will be forgotten about by the vast amount of people on here after a month or two, there'll more than likely be a hardcore following who play it religiously after that, probably 5 or 6 people at a push I'd say. Look at the Black Ops II thread, it's the same 4 or 5 people posting in there and playing together compare that to the beginning when there was all the hype and everyone trying to organise gaming nights. I wouldn't put too much thought into running the crew etc as I'm sure most people will just invite their mates from their friends list without even bothering to log into the Social Club to look up stats.
