None, I bought most of my games directly from the retailer, and the ones I bought using a software like steam was FIFA and that gets downloaded on Origin.

I currently have 241 games on my Steam account. I have bought some of them from sources like Humble Bundle and key sites like Green Man Gaming, though. And, thanks to those amazing sales, I've really played a lot of great games for dirt cheap.

[TyranBrulee]

I have 615 games in my library and about 90 of them installed.
I've only paid for 162 of them, though. The others are from friends.
Steam sales are awfully addicting :/

[DjoBoy]

I only bought 3 games which are Counter Strike: Source, Garry's mod and Left 4 Dead 2. If I had more money, I would have more games, but now I'm a student. :-/

A friend of mine was on me all the time of get a steam account and at first I didn't. Then one day I thought to try it out and see how it is and I have to say it was a great suprise. Practical and many good games. Good times.

I bought like 2, I'm not a big fan of buying games.

[Theorus]

I have about 50 games on my Steam account at the moment, but most of the games came in bundles or were free.
I bought the Saints Row Bundle, Steam Complete Pack, and some others.

I have four that I've downloaded.

• Audiosurf is the first I downloaded. It's the game that I play the most on there. Nothing against the rest of my games, but there's just something about it that's more entertaining than the remainder of my library. I have Audiosurf 2, but I've tried that and haven't exactly gotten the hang of it. (Hold down the arrow keys? No thanks.) I play with the Casual characters and avoid the gray blocks. Done a few games to try to get red/yellow block bonuses in the past, but apparently 95% of the blocks doesn't work.
  
• Borderlands 2 was a game that one of my friends bought for me as a gift. I haven't gotten to Sanctuary yet in that game, and I'll tell you why: I can't get proper aim to kill people off. I'm not polished enough to work the keys around yet. My friend has actually jumped in to play with me, and I keep getting second wind because there's something about the game that doesn't want to cooperate with me. I don't think it's the game's fault more than it is mine. Maybe one of these days, I'll jump back in and play it. But for now... Not yet, thanks.
  
• The other game is SimCity 4 Deluxe. Not an odd choice for me when I picked it, because I played it when I was in grade school, but I think me playing it in grade school doesn't equal out to me having the knowledge to play it in 2015. I've done Sim building games in the past (on Facebook), and I was kind of awful with those. I don't know what made me think that playing SimCity was going to be such a great idea. I haven't touched it since I bought it and played with it that night.
  

Maybe if my friend convinces me to get another game, I'll get one or two more. Now, though? Not so much. I'll stick with what I have.

I have about 20 games, my boyfriend has over 100 games on Steam. :p We really enjoy Steam and the ability to share games if both accounts agree and also that the reviews are pretty awesome of each game. Plus, we just like the Steam interface in general.

[SpartanScooter]

I have 125 games on steam, but at least a quarter if not a half of them are from bundles. The rest I either got gifted, or bought cheap during sales.
