it still sold 1 million in its first two months retail.Yeap but the last position Dark Souls 3 probably sold more across all platforms and the chart includes digital for Dark Souls 3 and not for Uncharted 4.
If I have to make a guess:
DSIII 1.7-2.0m with digital (PC included)
U4 1.5-1.8m without bundles and digital
The numbers could be close with U4 being ahead if they included digital + bundles.
