Ok, this is my rough estimation of game backlog at this point. Thanks a lot, career. I own all these games either for PC (Steam, mostly, or Origin), or PS4, and have not beaten any of them (except where I note an exception). Most were purchased for serious discounts during sales.
Priority:
GTA 5 (PC version) (this constitutes a 2nd play through but it's too awesome on PC at 4k not to play)
GTA Online (I'd like to finish the heists and level up my character a bit)
Far Cry 4 - I'm about halfway done the main quest
Dragon Age Inquisition - I've put in about 10 hours into a 200 hour game
Crysis 3 - I've played only the opening level
Witcher 3 - I've gotten about 2 hours into this one, another 200 hour game.
Mass Effect 3 - I got a couple hours into this one but it was on the tail of replaying Mass Effect 2, and I couldn't take more of the same, but I need to go back and finish this.
Mercenary Kings - I was playing this multiplayer with friends. It's an Indie gem. We got about a quarter of the way through it.
Max Payne 3 - Have played maybe halfway through it. Very solid, and gets bonus points because Max Payne 2 was an all-timer.
Suikoden 2 - A legendary Japanese RPG originally for PS1, re-released as a classic. Remember from when I was a kid. Need to play this.
Non-Priority but I'd like to play soon:
State of Decay - another Indie game, I've tinkered with it, really stellar for it's budget, but it's another open world game I don't have time for.
Dishonored - Heard great things. Played the first half hour or so. Seems cool.
Watch Dogs - Purchased for $60 bucks on PS4, played maybe 10 hours, haven't gone back because it couldn't hold my attention.
Deus Ex: Human Revolution - Again, heard great things. Haven't touched it.
Alan Wake - played through maybe half of it. Part of the problem is I can only play it during the day.
LA Noire - Another game that got solid reviews but just isn't good enough to creep higher on my list.
RAGE - See LA Noire. It's graphical problems contribute to it's status here.
Tomb Raider - Played about half. Got sidetracked. I'll go back... someday. Probably have to start over cause I forget all the controls.
Witcher 2 - Jesus, just no time. Not as good as Witcher 3 so it gets buried.
Dead Island - Another good co-op multiplayer game that we don't have time to finish as a group.
Apotheon - Another amazing indie game, that I'll get to when I can.
Games I'd like to tinker with once I finish all of the above:
Torchlight 2
Saints Row the Third
Tropico 4
Dragon Age Origins - Have never touched this game despite it being a "great." Probably will never get to it.
Titanfall - No single player means I'll put in a couple more hours of Multiplayer and call it a day.
Assassin's Creed 1, Assassins Creed 2, it's expansions, and Assassin's Creed 3 - Got them all super cheap on a sale. Maybe someday.
Every PS+ game I've downloaded since getting the PS4 in December 2013 that I haven't put much or any time into.
Games I'd like to beat again because they are awesome or because I want achievements:
Red Dead Redemption - I 100%'d this game, but I don't have the Platinum trophy. I'd probably need to put in 40 hours of multiplayer to get it.
Last of Us Remastered - Need to platinum this game too.
Fallout 3 - Only played this once. Unlike Skyrim which I beat with multiple characters.
That's all I can think of right now. I'm sure there's more. And I left off plenty of games that I know full well I'll never play or have limited interest in despite owning.
