How many of the games in your library you never played, how many games you completed?

not counting DLC, but instead looking at my library's install count:
owned games including F2P and betas: 279
games completely beaten (100% achievements if available): 30
completely unplayed: 87

first world problems.

I am stuck in a few. Some i got really far but did not finish. It will get better once I finish school. games I finished(oos is outside of steam): coh(oos), hitman 1(oos), doom(oos), universe at war(oos), dawn of war 1uo to dark crusade(oos),portal, wolfenstien 3d(oos) Games i got really far on but I have not finishd but plan to: gta 3, gta vice city, gta 4, gta san andreas, hitman 2, mafia, return to castle wolfenstiens, sniper elite

I finished only MW3 Multiplayer :D

I'm complete not so many games (about 15) and never played many games from indie bundles. Complete with 100% achivement only Darkness 2.

Out of all 89 games on steam....
I have finished 21 of them. A few more if you count games like skyrim that don't really end, but have main stories that you can finish.

Most of the rest are either things you cant finish, like tf2, but there are a fair few I simply havent looked at, or got bored with.

I currently have... 20 games I havent played! Wow... I didn't know it was that much. They're mostly from indie bundles.

I'm waiting to finish Counter Strike 1.6 .. when I do that I will probably play some of the rest 70+ xD

I finished The Secret of Monkey Island: Special Edition, a couple of Sam & Max episodes, Peggle Deluxe and Peggle Nights, and Faerie Solitaire. Played quite a bit of The Wonderful End of the World, Plants vs. Zombies, Ghost Master, Everyday Genius: Squarelogic, Defense Grid: The Awakening, Trials 2: Second Edition. Quite a few other games I played a few hours, like Mirror's Edge, UT3, Prince of Persia, Tomb Raider: Anniversary. Some just an hour or two, some just a few minutes. Still probably haven't even installed over half of the 137 games I have listed on Steam.

Approx 612 Games.
Completed: Only counting games that have singleplayer maybe 40.
Maybe 450 Games or so I never even downloaded.
About 5-15 games that i played for achivements during sales.
About 20-40 games that is Multiplayer focused games that you never can complete.

Of my 121 steam games, I have only 87 installed :3, this is mainly because I am limited to one gig a day and my speed is about .1-.2mb/s -_-. Of those installed I have not played 47 of them. And hav only finished a total of 6. Bare in mind many of them are open ended, as in no clear ending. Such as CS, Terraria, Nation Red, Garry's Mod, etc.
Top game: Terraria. Time played: 89 hours.

I consider a game 'completed' if I feel like I have seen all the content worth experiencing in it. For some games this takes 20 minutes, others it might take 40~ hours. If the game is worth playing it usually means completing the main storyline, but some games don't have such things.

That said, I have completed most of my games, and I have almost 30 I think in my backlog. Some I have played briefly and am coming back to them, but they are all 'incomplete' for now.

I did the same thing until i realized that is better to keep points for your wishlist games

I own 21 and haven't played 10 of them and haven't completed any of them. I can't even complete Portal, My friend says I don't have the mouse skills! D:

I have 20 games I haven't played and I've completed around 30 of the 300 games I have.

38 not played...and...like...3 completed?

The list is too big to compile atm, but I'm trying to maintain 100+ hours every 2 weeks (with minimal idling), currently I'm a bit low but that's alright. I'll get through them sooner or later.

most of my unplayed games are crap. No way I am going to finish Beep

I've got games with 200+ hours on them, like Torchlight and TF2, that are technically not "complete" but where you can't really ever finish. I've also got games like Fallout 3 (146 hours) and The Witcher (114 hours)where I've completed all I want to do.
Then there's games I've barely touched but plan to finish. Picked up cheap for a rainy day or when I'm in the mood as it were. Bioshock 1 and 2, Mass Effect 1 and 2, Dead Space 1, Metro 2033, etc. All massive games which I haven't yet got the urge to play.
I started Fallout New Vegas but kinda went off it. I'll be back. :p
I've got a lot of smaller games from indie bundles which I haven't played yet either.

honestly I almost never finsh my games due to never wanting them to end.

37 that I've beaten and 35 i haven't played. Most of the games i haven't played i got from indie bundles.

I only completed Portal 2

got like 100+ games, played like 10...

I have 517 games (according to steam calculator... according to steam i have 804) i've finished 317 ive started but never finished 62 (+ a lot of multiplayer only titles 40) which leaves me... 98 unplayed

not too shabby im probly +/- 12 or so...

so hard to remember them all

ONLY FINISHED PORTAL 2 LOL

i have 130 games and played like only half cuz thos are multiplayer games or there was christmas archivement
