Darkest Dungeon released in 2016 and still gets my vote, I’ve easily put the most hours into that game this year. The excellent early access sort of makes it a 2015 game, but the amount of incredible support given to this game and attention to detail to scale the difficulty without taking away the experience cannot be overstated. I look forward to the soon to come DLC, which will bring in a Van-Hellsing inspired hero and new locations involving vampires.
