Hmmmm.. I know that Dishonored games and Prey don't or didn't had big numbers, but they sold still pretty good.. Dishonored 1 on Steam sold more than 2 mil. copies, who knows how much on consoles.. Dishonored 2 sold on Steam more than 1 mil. copies, again I don't know the numbers for consoles version and Prey has on Steam more than 500k copies sold - not great, but still for such a title good numbers, and that is only PC
Compared to Vampire Bloodlines, which few months after release had only around 80k copies sold
