It's been a weird year for me. I've found it to be pretty underwhelming and almost nothing has stuck with me from the years biggest releases.
Witcher - Standard Fantasy games games have bored the pants off me for years, and it's hundreds of hours so to hell with that.
Bloodborn - Played 20 - 25 hours or so REALLY trying to like it. Definitely did not.
MGSV - Never cared about Metal Gear so I didn't play it. It does sound pretty cool but I'm pretty burned out on open world games as they tend to waste the fuck out of the players time and I'm just tired of it.
Basically, the most fun I've had this year was Rocket Legue and Helldivers (on any difficulty until the point where you start fighting enemy armour. Then it gets not fun...)
