When PS4 has a huuuge user base of almost 80 million.. its exclusive games better sell at least 8-10 million. Nothing impressive to me.
Because exclusive games on the PS3/360 regularly sold 8-10m right?
No 8-10m isn't the norm just because it's selling to a 75m installbase, (around 55m at launch).
Even Wii games on that it installbase such as SMG2 didn't reach the 8m mark.
LTD: PS4 - 125m, Switch - 110m, XBO - 51m
2020: PS4 - 9m, Switch - 22.5m, XBO - 2.5m, PS5 - 4.5m, XBX - 2.8m
