5) Rocket League - Still maintains a fun experience, merging skill and chaos.
4) Gone Home - Great story that started to make me feel things. Short length is appreciated, as if they developers respected their story and my time.
3) Super Hot - Rad style points.
2) Mario Kart 8 Deluxe - Only had this for a few days, but playing 4 player split screen with my wife and kids has been a highlight of the year, easily. So much laughter.
1) XCom 2 - I really enjoy the laid back nature of turn based strategy, and the leveling progression between the characters and base massage some pleasure receptors in my brain. This was very challenging and not without some losses, which is always weird to accept failures. The battles in this game sort of have random elements that lend themselves to making personal stories to remember and share with others.
Biggest Disappointment: The Witness. I didn't feel like this game respects players time. I can appreciate the presentation of not having overt tutorials, but there is something really missing here. I feel like I made progress but didn't learn something that should get me past the next puzzle. Because of the high praise this game receives I may give it another try someday, perhaps I didn't want to give the game the patience it demands.
Special nod: Dead by Daylight. Played it on a free weekend. The game is pretty buggy and seems to have similar game play to the Friday the 13th game. It is maybe almost hide and seek with a B-level horror movie game. I really enjoyed playing as the killer and stalking 4 other players. Killing the campers almost felt like I was trolling them, because you have to hang them on hooks spread out over the level and they can't do anything for like a minute while their comrades have a chance to rescue them. So sometimes I would hide around a corner and wait for a new victim. Even when people quit out when they get hooked I still got bonus points for making them quit. Just lots of fun to be had with a simple game formula. Hope to see someone do a horror game like this, but with better performance.
