Top 5 time? Top 5 time!
To be honest, I was going to include Assassin's Creed IV Black Flag on this list, since I played the JP PS4 version which IS a 2014 title, but since it was released everywhere else in the world in 2013, I'll let it slide for now, just so I can include:
05. The Evil Within
Hugely underrated and misunderstood, mostly because it requires you to use your frecking head instead of your trigger finger. It's not RE4, no, but it's a damn great game that only Mikami could have come up with.
04. P.T.
Holy shit this is the scariest thing I've ever played in my entire life. I literally, LITERALLY had to put down the controller to calm down at some point. Love it.
I'm sure the final "Silent Hills" game will be nothing like this, which is why I think this "playable teaser" deserves a spot on the GOTY list: it made people talk (and scream) and it made a dying franchise relevant and exciting again.
03. Kingdom Hearts II.5 HD Remix
Because it is a collection of the two best KH games, and they look gorgeous and still hold up fantastically well.
02. Bayonetta 2
Because it is the pinnacle of the action game genre AND it comes with a port of the original FOR FREE.
01. Theatrhythm Curtain Call
With ALL of the songs of the original game (including the DLC ones!), plus a metric shitton of new ones, and FINALLY some non-FF music available for DLC as well, oh AND a hugely improved Quest Mode (because let's face it, the Dark Notes thing in the original was kind of disappointing), this game has toooooons of content to keep you busy for at least 100 hours.
There's nothing I spent more time with this year than this game, and that's because it's absolutely unparalleled and perfect at what it does.
