"Since it hasn't been mentioned at all in this thread, I would like to take this opportunity to highlight the optimistic sales of NBA 2K15, the #1 seller of the month. It has done well, taking advantage of next-gen momentum to grow the franchise.
Believe it or not, NBA 2K14 (its predecessor) actually launched in September 2013, selling approximately 0.6 million units opening month.
It only had 5 days in the September tracking period, with the remainder realised in the 4-week October 2013 tracking period (approx. 0.95 million between September and October).
NBA 2K15 managed 1.1 million units in the October 2014 4-week tracking period, which was 17% above the combined September 2013 (5 days) + October 2013 sales of NBA 2K14.
NBA 2K14 was -23% from NBA 2K13, so to see the franchise grow 17% this year is a positive sign."
