Kind of like a hardcore mode, stuff like that.

Maximizing sales? That might be so, depends on the investment deal that is struck, if any.
Since games are published by a publisher, like EA or Ubisoft, I believe the ROI is of course important, but they won't cut the margins just to get the quick fix.
There is no continuity in the long run if you do business like that.
