Final Fantasy 15. I've never been a fan of the modern (post FF7) games but fell for the hype around 15, purchased it, played it, actually finished it constantly wondering when the game would suck me in, and was left wondering what all that hype was about. The game had literally nothing I wanted in a JRPG as I found the story bog standard and the combat and traversal piss poor. That game officially made me give up on Final Fantasy since the only recent-ish game I've liked is FF Tactics. Make a sequel to that and I'll reconsider.
