People also need to recognize that Batman targets a more mainstream audience than a game like Bloodborne. BB tore up Amazon but in the same month the mainstream targeted BH:HL outsold it despite being dominated on Amazon.
Chances are that Batman % wise is doing more business at traditional retailers than a game like BB. My point being the gap created by Batman for the PS4 should be even larger once we see traditional retailers come NDP.
add me, the more the merrier.
