I want to buy a PS4 for Horizon Zero Dawn. That game looks epic!
It's extremely good. It basically rekindled my love for video games after Mass Effect: Andromeda nearly killed it.
That said, the best game of the year is Nier: Automata. That's a 40 hour game that blew my mind on average about once every 90 minutes. The true ending credits (there's a ton of endings, you have to play through the game like 3.5 times to get the true ending) had me both smiling and had tears streaming down my face at the same time. I bought the soundtrack because it's so good, and the day after I finished the game I sat in my car listening to the ending credits music and full on ugly crying.
... It's a really good game is what I'm trying to say.
