Skyrim, heavily modded; Farting Shouts at Macho Man Randy Dragons never gets old.

Oxygen Not Included: base building and resource management. What appears to be a cutesy and simple resource/survival game that turns into a horrible faceplant into thermodynamics, pressure modulation and oh so many deaths. Can't recommend enough. Same folk who made Don't Starve.

Sunless Seas: Fan of action? Er, this ain't your game. Heavily atmospheric and brilliant written game about slowly going mad and maybe eating your crew.

City of Brass; First person Rogue-lite with an Aladdin feel. Bloody hectic.

Darkest Dungeon: IMO the absolute best 2D sidescrolling Dungeon crawler RPG with RL elements, amazing soundscape and narration, heavily RNG based though. Must buy for anyone even remotely interested in what I just wrote, and a sequel is in the works too! Can't wait.

Crawl: 1-4 player 3v1 RL with a unique mechanic I don't wanna spoil. Watch the trailer even if it's just for the amazing voice acting in it. Literally what compelled me to buy it.

Laser League; Lesser known futuristic sports Sim, didn't really take off unfortunately. 2nd only to Crawl for Couch Co-op with a few beers.
