To be fair most Sony AAA exclusives title aside from uncharted 4 (come on) and bloodborne has failed miserably financially imo. I think Microsoft exclusives are doing better.
I thought inFamous:Second Son was a pretty big success since it sold over a million copies within a week. Even Killzone sold over 2 million, and Knack sold over a million.
Isn't The Order the only title couldn't even hit a million, and now SFV which is Multiplatform.
