Continuing the discussion from Valve is not your friend, and Steam is not healthy for gaming:
To avoid derailing that topic too far, and also so that it doesn’t get lost.
I’ll Start:
https://steamdb.info/calculator/76561197963133553/?cc=us
820(!) games, 691(!!) unplayed.
Somehow I’ve played over 100 hours of the original Plants vs. Zombies.
Game I should probably play more: Axiom Verge
Game I should probably start: Kentucky Route Zero
https://steamdb.info/calculator/76561198103076183/
Best games I haven’t played are probably:
Far Cry 3
Far Cry 3: Blood Dragon
Injustice: Gods Among Us
anything Tom Clancy

Not really accurate since I have a program that farms cards from games. I then use said cards to get credit to buy more games.
Currently I have 541 games 
Mine is very unimpressive:

If there was one for Xbox or PS it would be a far different story.
Hahaha.
/me looks at massive stack of games
Yeah. Backlogs exist. But I think us game hoarders are doing future gamers a service by archiving copies of games that will no longer exist in five, ten years. (Try finding an original copy of GTA: SA now - it’s hard)
Here we are:

I’ve actually spent far less - either from bundles, freebies, giveaways or using Steambucks from trading cards (I have to give Valve credit there, for creating something fundamentally useless like trading cards and finding a way to make money from it).
Then of course there’s my Playstation backlog, GOG/Origin/Uplay accounts and who knows what else…

I’m getting pretty good VFM there. I have really latched onto a few games.
I also noticed it thinks I spent 2 minutes playing Half-Life 2… but I’ve been through the campaign three times, and then once more in the enhanced edition.
Seems most people spent 5$-10$/hr? That doesn’t sound so bad, really. People bought a lot of duds in the good ole days, too.
Edit: actually, wait. If I played 128 hours and paid $207, how does that turn into an average price of $8.55 an hour? Shouldn’t it be only $1.60?
I can’t help but think that a perverse metric could be derived from the total time played, over hours lived. A true ‘proportion of life wasted’ score. 
(Of course, my inner optimist points out that time spent on leisure, active entertainment, and ‘recharging the mental batteries’, is in no way actually wasted. But that’s less fun 
)
(and then I’d have to estimate the fraction of my life lost to nethack. Awkward.)
nethack isn’t a waste of life, cuz when you die you just start over
oh wait
you mean real life
And sometimes generate a bones file.
Wait. ‘re-al life’…?
Nethack is the best. I played the hell of it in High School, on the school PCs and on my DS.
That’s some speed run! 
here’s mine. As you can see, I have saved BUNCHES from doing bundles and sales.
I give them props for that. I have gotten enough cards that I converted to Steambucks that I could probably have gotten GTA V at full price without paying any actual money.
Oh yes, I have that same issue. I do like that GOG allows you to link to Steam now. Just wish more publishers were down with that.

ETA I have one idle game that is a metric fuckton of the hours.
Hmm, biggest single contributor to the hours on record is Kerbal Space Program. Spaceflight takes time…
