This is actually a big achievement for the PS4 considering MS's biggest exclusive of the year realeased that week along with AC: Unity X1 which had a big bundle and a lot of advertising.
I'm getting sick of saying well done to Sony but this week you really deserve it for having the biggest release in the world on your system.
Well done.
