are people not going too far ahead?
GOW3 opened with over 1.1 million but its second month was not even 200k if i remember.
So 1.8-1.9 million first month is
mighty impressive but i will not bet on its legs.
It will be impressive if second month is above 500k.
To hit 10+ million i think you need legs like Crash or TLOU. and although GOW is a fresh start but it is still a new entry in the series and existing series launch do not behave like a new IP in legs department. I think
MatPiscatella or
Benji can shed more light on the legs of a new entry in an existing series vs new IP.
