Hmm... 1.4GB is a lot and this will mean that a lot of people won't join matchmaking immediately... so that might making matchmaking harder for the first impressions, definitely. That raises another question actually; what do we consider to be "ideal" matchmaking times? I could find games in Halo 4/Reach in under a minute, MCC takes 4-5 minutes when it works at all.
