Thanks to ArmGunar for the analyses.
Gamstat was nice and provided me some early numbers for Ghost (subject to change !)
Day 1 and Day 2 numbers are just my estimates, from what I see from the graph ^^
The only number provided is 2.00m players as of July 19th
If 2.00m players in 3 days is correct, well 2.3M-2.6M sold-through in 3 days is not impossible !
I made two tables to compare this
