Why did you show me two pics of Xenoblade Chronicles X? Obviously a sequel to an already established game is going to move the franchise toward the direction that the first game has, plus advances the director may feel necessary. I would gain nothing by showing you FF XIII pics, considering the massive difference from XII despite both having Final Fantasy on the name.
There's nothing definitive to support the presence of FF XII influence; but then again, the core similarities are there. For that, there's nothing to disprove that they didn't use FF XII as a reference either.
I didn't show you 2 pics of Xenoblade X, only one of those pics were of X. There were 2 from different Phantasy Stars, a Xenoblade Chronicles X pic, and a Xenoblade Chronicles pic.
I rest my case.
