What gaming clients (like Steam) do you use?

Only Steam, of course.

Desura, Origin.

Only Steam and Origin.

OnLive is really cool to run high spec game on any machine.

Steam & Desura

The only non-steam games I've bought in the last 5 years are Starcraft 2 and some games from gog.com.

Origin - Don't use it that much, I'd run it mostly for Burnout Paradise. Its not really bad, just needs to get some features like steam's community at the very least.

Desura - Thanks to all those Indie Royale keys and some of those greenlight bundles that I got, I decided to install it. Its not user friendly. At all. I got really lost when I first used it, you really do appreciate Valve's work on their client after you use desura's client.

Just Steam 'cause Origin can suck it. XD

origin only slightly buggy?
how about logging in to it only to see a message saying that someone else is signed into your account onto another computer and will be logged out,having to change your password only to see the same message, proceeding to download battlefield 3 only for it to take 14 hours,going to play it the next day, getting a message saying it is corrupted,attempting to repair it,then seeing that it is still corrupted, trying to uninstall it, but then it doesn't uninstall???
This legitimately happened to me this week.

Origin is the second best gaming client but that isn't saying a lot.
Since bio-ware seem to have lost their touch and have flopped with the mass effect and dragon age series, I can say that I wouldn't even have it if not for Battlefield

Desura is another client that is pretty good but is only for indies.

Steam is the only one worth my while. I have Origin installed, but haven't purchased a single PC game from EA, just play their titles on PS3.

Steam, origin and uPlay.

i have just steam,
one to rule them all

The One and Only Steam.
I don't like installing multiple clients only to launch a game.

I use Steam and Origin, but I realy hate Origin. Im just using it because of BattleField 3.

aaaannnd STEAM FTW YEAHH :D

Steam, Origin, Desura, uPlay.

Steam, Origin and Uplay, long time ago also Capsule, but that was mistake.

Steam and Origin...origin just because of Battlefield Bad Company 2 And Battlefield 3

Steam, Desura, Origin, uPlay (If you can even consider it one), GFWL... (because I have too T_T)

I don't mind Origin actually. I haven't had any problems with it and I've played a-lot of ME3 and BF3.
GFWL on the other hand... oh god, hnnnng.

Steam, Origin, but just to click "Play Battlefield 3" and Games for Windows live... when i have to, like in GTA IV

Steam for most of my games because the games are the cheapest most times.

Than I have some game on Origin. I like that the client is faster and that none of my games require Origin to play.

And I also use Desura for some indie games, mainly because many games have Linux versions and you also get direct downloads for the games so you don't need the client.

I wouldn't care when I have to use more clients (and DRMs), I just buy the games where they are cheapest, no matter what client/DRM.

Steam and Desura at the moment. I'm a bit reluctant to download Origin or uPlay unless I have to, but I don't think that if I decide I really want a game which requires either it'd put me off buying it.

desura n steam.

I only use Steam at the moment. This is mostly because my current laptop can't handle much gaming.
I will probably be forced to use Origin, if I want to play titles like Crysis 3 or Battlefield 4 when they are released, and I have a PC capable of running them.
