I wonder how many people that bought Ghosts still play it though? PC went from 30,000 at a time on average to well below 8,000. There was just 850 on two days ago at one point. Barely any people on here play it anymore from what I've read.
At the end of the day, it doesn't matter how many copies it sells; it's how good the game is and I didn't like Ghosts but I think they'll bounce back with COD AW.
