Apparently the last record holder for MS was Quantum Break.

^ this is important.

VGCz estimates Quantum Break sold over 267k units at retail (over 300k with digital).
So we know that atleast 300k people "bought" Sea of theives for 60$ (full price).

Why are there quotation marks in between bought?
