I'm pretty sure it's due to how the Japanese market pretty much trashed it. While Japanese reviewers such as the magazine Famitsu gave it great scores, many people spoke up saying it was terrible. People are naturally taking any negative they hear over the good. It doesn't help that several news outlets in the states have already agreed that with the fact that the game isn't very good, then again most RPGs in terms of reviews don't do that great over here.

So it's a matter of perceptive and influence. It's naturally going to happen.
