Well I've been playing for a while now and it is definitely growing on me. I haven't had any issues with lag or anything related. I had a number of lost hosts and such with MW3 leading up to a week before Blops2 came out. I am truly enjoying the MP and gave the zombies a whirl for one match today. Campain is still ok, but I'll be glad when it's done and I can say that I completed it.
