None of these are my least favourite game, but I don't like any of them, especially in compairson to past titles:
Ratchet and Clank (2016): Absurdly pretty.
Witcher 3: Obviously a huge, well-managed project with a lot of love and effort thrown behind it.
FFXV: Good dungeon layouts, for the most part, and excellent monster designs.
FFXIII: Great soundtrack.
FF Type-0: The first cutscene is pretty good.
Tales of Zestiria: Skits are relatively strong.
Dragon Age 2: Neat frame narrative.
Nier Automata: Gorgeous music, with some nice, bittersweet sidequest vignettes.
GTAV: Absurdly content-rich and fleshed out.
Shadow of Mordor: I platinumed it for some reason? I can't actually think of anything I liked about this in retrospect.
