I had a lot of fun with Vanquish and Nier is really a AAA game in a B suit. I would be all over the the PS4 or Xbone if it had a sequel at launch. It's biggest weaknesses were combat being kind of shallow and the art style looking PS2.9.
It doesn't bother me. Zero Dark Thirty, Band of Brothers, are based on a true story too. I didn't witness any of those events and all my knowledge of them is second and third hand at best. Hell in about five years you'll be able to put "Based on true events" in front of Robocop.
