PS4 FF Type-0 was #55 for February: http://www.amazon.com/gp/bestsellers/2015-02/videogames/ref=zg_bsar_videogames_pg_3?ie=UTF8&pg=3#3
And yes, preorders were higher than sales from both versions of Evolve.
And I don't see the XBO version in the Top 100. Any idea where it was in Feb? I can't seem to check beyond top 100.
