… and a 1 sentence only explanation as to why.
Fallout 4: I've played all the Fallout Games barring New Vegas and despite it's many shortcomings for me it's a solid Fallout game that I still haven't finished.
Grow Up: It makes me grin like a little kid :D
Dark souls 3: Interesting lore/story, excellent combat and moderate difficulty.
Witcher 3 Blood and Wine Expansion (if this counts) : Amazing game with great content added, easily worth the money spent.
Otherwise 2016 has been a pretty bad gaming year for me :(
