Long tail sale wise?. because 2017 is telling a different story and trend now.
Hard to say in the long run... but 2015 to end of 2017... so far its PS4 > PC > XB1.
That could well change over time (in the future), because it does look like its now selling more on PC than PS4 (going by 2017 numbers).
