Looks like Marvel's Spider-Man has sold over 20m units worldwide, making this one of the best selling games on PS4.

Was a good choice to work with Marvel and Insomniac to get Spider-Man on PS4. Certainly paid off.
Even better to acquire Insomniac for $229m in November 2019. https://t.co/qNBbjYDq39
So Sony are not making any fanfare regarding the 20m milestone, so probably more 1st party games will quitely pass the threshold if they haven't already
They will potentially have 4-6, 20m+ selling exclusives by the time PS4 is discontinued. They're selling 1st party titles at near Nintendo levels
