Probably about 400 games

I wish for a year long vacation with my pc so I could finish all my backlog, but half of it would be impossible to finish. As much as possible I'll stay away from any discounted sales and promos, but in the end I always give in. Another culprit of my backlogs is Steam free to play weekend, I ending up buying the game and GOG's excellent promos.

Currently using cheats, like godmode just to finish a game.

I'm going to quote OrcishGamer and say: On the other hand, I do have some decades worth of gaming materials, though not the time needed to play them.

Currently working on Shin Megami Tensei: Strange Journey. Aaaaallllmost done, but still probably 30 more hours knowing how I tend to poke around.

The rest of my backlog looks something like this:

9 Hours, 9 Persons, 9 Doors
The Dark Spire (made it to floor 5... and I'm lost, no idea what to do next)
Dragon Quest 6
Dragon Quest 7
Dragon Quest 9
Fianl Fantasy III
Ultima 5
Ultima 6
Ultima 7+SI
Ultima 8
Anachronox
Baldur's Gate 1
Baldur's Gate 2 (already pretty far, but probably nowhere near completion)
Icewind Dale 1 (also pretty far, but nowhere near halfway through either)
Icewind Dale 2
Planescape Torment
The two expansion packs for Morrowind
Full Throttle
Psychonauts
Fallout 1
Fallout 2
Wizardry: Tales of the Forsaken Land
Shin Megami Tensei: Digital Devil Saga 1
Shin Megami Tensei: Digital Devil Saga 2
Shin Megami Tensei: Devil Survivor Overclocked
Vagrant Story

I'd get through these quicker if I wasn't working a full time job during the day, and working on my own game in the evenings.

I have 4,500 games and have completed about 1% of them.

So seeing this a backlog is pointless, as I'll never finish them in my lifetime. I see it as an extensive collection of games from which I can choose at will.

Mine's not too bad right now actually (except for the fact that many of these are really long games).

GOG:
- Planescape Torment
- Baldur's Gate 2
- Jagged Alliance 2
- Icewind Dale 1 & 2
- Independence War 1 & 2
- Neverwinter Knights
- Ultima VII
- Ultima Underworld 1 & 2
- Theme Hospital
- IL-2 Sturmovik
- Dungeon Keeper 1 & 2
- Alpha Centurai
- The Blackwell collection

Other:
- ARMA 2
- Dawn of War 2: Retribution
- The Walking Dead (waiting until ep 5 is out until I play through it all)
- Silent Hill: Downpour
- The Ratchet and Clank trilogy HD collection thing
- Orcs Must Die 2

I think IL-2 Sturmovik and Dawn of War 2: Retribution are the next ones I'll tackle.

Couple of hundreds. Don't know exactly, but I'd guess 200-300. That doesn't include the free games I want to play.

I can't imagine I'll get to any of them any time soon. Though I've been cutting the backlog on my Nokia 6120c. I finished (the mobile version of) Oblivion recently and now playing CSI New York.

According to my Backloggery , I have completed 51 of my 489 games.

Ah yes, quite ! :) 41 Beaten, 10 Completed ;)

A Backlog of about 800 titles at the moment, but I don't really complete any game, no time for this ;)
