Similarities to Game of Thrones

So I am totally late to the party....I got the game day one, but only just started playing it earnestly this month......

is it a coincidence that the story/atmosphere gives off a similar vibe to GoT?

I'm sure this game started development at the peak of GoT popularity, but i didn't know if that was a direct inspiration or just a coincidence.

just curious more than anything! been really enjoying the game so far!

like i've been recommending this game to friends that are both FF and GoT fans.
(I like to think it's a perfect blend of GoT, FF, and a pinch of Naruto)

(I'm about 2/3 thru the game now going by the Chapter Titles)

thanks
