Doom 2016 was an incredibly fun game, and its focus on pure gameplay is a big reason why (a story is there, but is mostly window dressing). The core gameplay loop was immensely satisfying as it encouraged an aggressive in-your-face play style. Camping would get you killed. And it did this while also retaining most of what made old-school Doom fun, while adding some more modern FPS accoutrements (e.g., ledge grabbing, upgradable abilities & weapons).
Definitely my favorite non-Nintendo game of the generation so far.
