Still planning on getting a lot of games.

I'll add more later. That's from PSN. It's really cumbersome and some stuff I don't remember buying. Other stuff isn't showing up.

My Xbox downloads should dwarf my PS list, too.

*Shrugs*

Uncharted: The Nathan Drake Collection
Uncharted 4: A Thief's End
Deus Ex: Mankind Divided
Dishonored
Dishonored 2
WWE 2K17
Call of Duty: Infinite Warfare w/ Call of Duty 4: Modern Warfare Remastered
Ratchet & Clank
Saints Row IV
The Division
Tales from the Borderlands
Rise of the Tomb Raider

I didn't really buy too many this year, off the top of my head from what I can remember:


PS4:

Uncharted 4: A Thief's End
Borderlands The Handsome Collection
Tearaway Unfolded
Injustice: Gods Among Us Ultimate Edition
Grand Theft Auto V
Batman: Arkham Knight (was a gift for my birthday last January)
Dark Souls 3
Ratchet and Clank 2016
Let it Die (Free to play game that just released a few days ago during PSX in case you don't remember, haven't played it yet though).

Games I got from PS+:

Transformers Devastation
Resident Evil HD
Helldivers

And then on Steam I think the only games I actually bought in 2016 were Geometry Dash and Blockstorm. I mostly just stick with games like TF2, CS:GO, etc currently because my laptop can't handle too much so I don't buy much big games on Steam currently.

From what I can remember:

Fire Emblam Fates: Special Edition
Bravely Second
Tokyo Mirage Sessions #FE
Ace Attorney 6: Spirit of Justice
Paper Mario: Color Splash
Pokemon Moon
Corpse Party 3DS
Azure Striker Gunvolt Double Pack

I plan to get Shantae: 1/2 Genie Hero, whenever that decides to come out >_>;

Dark Souls 3
ROTK 13
FFXV

PS Plus Games.

Was broke until September this year, then I bought FFXIV while it was on sale. Still pretty low on money, considering World of FF and Digimon if they go on sale.

I'll probably forget some.

Uncharted 4
Dark Souls III
Ratchet & Clank
Titanfall 2
The Last Guardian
Batman Return to Arkham
Paper Mario Color Splash
Pokemon Sun

Tearaway Unfolded

Resident Evil Revelations 2
