How comfortable are you with Digital Distribution?  
  
Steam has been my main venue for purchasing games since 2004, I've got 185 games purchased through Steam + a couple dozen gifts.  

only 77 :P

124 according to my community page.
 
I love it. Steam is solely responsible for my current PC gaming habits.
 
Not sure why my Civ 4 and expansions show up twice. I hope I didn't buy that pack twice... (edit: one is http://store.steampowered.com/app/3900/ and the other is http://store.steampowered.com/app/34440/ that forwards to 3900. weird.)

I only have 18 games in my Steam library, sadly I can only keep a certain number on my machine at any one time.

None.
 
Boxed games ftw!

i have like.. six games

Uh, like 80 in all I think.  I'm too lazy to check.

I'm sitting at 156. A good chunk of em came out of the THQ Complete Pack, and almost all of them are from sales.

I only just started using Steam after recently replacing my old computer so I can now return to PC gaming after a few years of consoles.
 
I'm currently sitting at 7 games, but it's quickly growing.

I am currently sitting at 38 games.

If you have had steam for more than 56 seconds and you don't own at least 40 hundred games you are doing it wrong.  
 
steam sales are like crack. its actually kind of fucked up.

" None.  Boxed games ftw! "

a ton, 14 :) but i love steam. I'm a newbie when it comes to pc gaming

2!
Portal and the Audiosurf demo.  My computer can't run Portal, and Audiosurf runs poorly.  The only reason I got Steam was to get Portal when it was free.

" @ajamafalous:  Ah... weird. I really thought I noticed it duplicated well before the Mac Steam thing. Plus no other multiplatform (weird calling PC- Mac that) games are duplicated. "

168 I think... not in a position to check at the moment.

a somewhat modest 33, though i do much prefer my video games in boxes. however, i am helplessly addicted to steam sales.

86

I thought I was crazy with my 153 games (some of them are duplicates though), but I see that it's rather common to have that amount.

84 on Steam, 8 on Impulse, and 5 on the EA store. This is not enough, I need more.

8. I have a crap computer so I can't buy many games from Steam. 

I'm at 207 right now. Now, as for how many I've played, that's a whole another story. Someone needs to take my bank card away from me when the deals come around. 

78. 

12 installed, 18 total. Thankfully, being that my computer is 8 years old, I don't have to succumb to many of the temptations that Steam provides.

" I thought I was crazy with my 153 games (some of them are duplicates though), but I see that it's rather common to have that amount. "

I have...five games:
-Civilization IV 
-Empire: Total War 
-Europa Universalis III
-Medieval II: Total War 
-Rome: Total War
 
I also own all the expansions for those games but I don't count them since they're really a part of said games. My computer is junk so I can't run almost anything that has released in the past four years or so. Empire: Total War pretty much just sits there unused since it's unplayable. When I finally get a new computer I'll probably get quite a few Steam games of things I've been wanting to play for years and can't. While I personally prefer physical media that's kind of impractical with PC titles since once you activate them the discs really arn't important anymore.

350 games. :o

I only have the Orange Box and Kotor

I don't have a steam account. 0

My library of 15 is very small compared to a lot of other people's libraries. I don't understand how you could have a Steam library so huge!

Only 21 games.  Would be more, but it costs money.  If anyone wants to give me some money, I'll gladly increase my Steam library.

68

I have 174 games on steam... I haven't played alot of them though.

58

And here I thought I was a big man with my 66 titles. 

31 and 11 in my Wishlist.

I have... about 53 or so. I have a few HL2 mods in the mix so that kinda skews the list a bit.

Think I'm somewhere around 90 now, most of them regular ($40-$60 range) games bought on steam.

85 games for me, Steam sales are deadly.

58 and growing. Steam is the only reason I game on my PC. I love it!

30 game so far which is kinda a lot seeing as i only signed up in May for free Portal. Cure you Gabe Newell 
 
My Games

6 Steam games + 1 Starcraft II. I don't buy many games though. I'm the type that buys a few games I really like and play the shit out of them. Digital distribution is definitely my preferred way of buying games and I love Steam.

I have 23 games in my library, but only 9 are purchased; the others are free. From those 9 that I purchased, 4 of them were part of a LucasArts classics pack that was like $5.
 
My rule is that a game should be $5 and less for a purchase on Steam. Though once I did spend $10 for Killing Floor because I thought it seemed good, boy was I wrong. It's a dumb grinding game where the developers have just abandoned it. Out of my few purchases, the Killing Floor purchase was the worst; a pathetic game and purchase, I remind myself of it so I don't make the same mistake again.
 
Why? Because with Steam you can't sell the game, you can't get rid of it for some money back. That's the worst part about Steam.
 
It's stupid... game companies have DRM that says you can install it on up to 3 computers (or some other number) ... but how can you do it with Steam? It's tied to your account? So it's stupid. You're going to share your password? Steam locks games to single users, you can't share or trade or even sell....... Steam is very restrictive in this way and I can't support them with higher priced purchases.  I might as well walk down the street in search of a poor man selling bootleg games than to purchase an extremely restrictive product from Steam.
