That is pretty impressive numbers! Congratz to Cory Barlog and to the Sony Santa Monica Team. Sale numbers could easily be 4m+ by now because its almost two weeks after those sales.
Its crazy how good Sony studios are: Naughty Dog, Guerrilla and Santa Monica are big 3 for me at least. Hopefully Sucker Punch can rise to this level with Ghost of Tsushima after moving to new studio and are now 170+ studio and still hiring. Other studios are talented as well, but a little lower on my list.
