UnrealDelusion: For me personally it was Return To Monkey Island.
Definitly one of the gams I would put in the top section of the ranking list. I don't think it's the best game of the year, but the one which certainly had the most impact.
Even with it looks, it felt like returning home. And "home" is always good.
I had loads of fun with "Horizon Chase Turbo". It's amazing how addictive that game is.
After completing the campaign to 100% on PC, I did the same on the PS4.
Sherlock Holmes was good as well, along with some other adventure games.
But I think the game which I enjoyed most this year was
Marvel's Spider-Man - even after I alreaedy completed it on PS4 two or three years ago. I just love swinging around through the City, this is just the game for me.
