Here are the games I bought in 2016 and whether they were good or not: (this is just from my Steam purchases list, I forget what I bought elsewhere)
The King: Factorio.
Still in early access, but it's crack cocaine. They have stated it will never go on sale.
Gameplay Trailer:

Brigador- Good. Isometric arcadey mech game
God Eater 2 Rage Burst- Refunded
Event[0]- Neat. Indie FPS exploration game where you talk to an AI through a console in freeform text.
Duskers- Kind of neat, I'm not into roguelikes but I'd bet other people would really get into this. You send drones into derelict ships to collect resources using a command line interface.
Hyper Light Drifter- Good. Zelda Souls.
Dark Souls 3- Good, weak for a Souls game but that's better than most
Homeworld Deserts of Kharak- Excellent, a bit short and w/ some tech issues but I think it's as good as the original HW. Really recommend if you like Homeworld.
Firewatch- My GOTY, not everyone will like it, it's a american wilderness novel in FPS exploration/dialogue game form
Sunless Sea- The concept is good, the gameplay is unbearably boring. bad music
Warshift- Refunded
Abzu- Good music (same guy who did Journey soundtrack). Journey sequel that's not quite as good
Doom- Very Good
Kentucky Route Zero- Good (early access, 1 chapter out of 5 still left I think). I don't know how to describe it. It's an indie game about spooky weirdness in Kentucky.
Inside- Exceptionally fantastic visuals, okay gameplay. Limbo sequel.
Ashes of the Singularity- Refunded
Ori and the Blind Forest: Definitive Edition- Great. Metroidvania and the best looking video game ever made.
Stardew Valley- Refunded
The Flame in the Flood- Regret not refunding
Steam Controller- absolute worthless garbage
The Witness- It's ok
Invisible Inc + Contingency Plan DLC- Fantastic. Turn based stealth tactical roguelike with 80s spy vibe (or 70s? 60s?)
Sattelite Reign- Refunded
Broforce- Refunded
XCom 2- Regret not refunding
edit- somehow I forgot:
Anno 2205- Utter and complete garbage. 2 steps forward, 10 steps back. Fuck them
