[EXTREMELY IMPORTANT] Which and/or how many game launchers do you use?

I've got too many games on Steam so now if feels like there's no need for other launchers.
Other than that I still play console games so there's always variety there.

Currently:
Steam (obviously)
Epic Games (Fortnite and the other freebies)
Battle,net (Overwatch, maybe WoW again someday)
PortableApps.com (Powder Toy and 2048)
Twitch (fMinecraft [used to be the Curse Launcher])
7D2D Mod Launcher (modded 7 Days to Die)
Nexus (modded Steam games [usually Bethesda games]]
Windows Store (don't use/play but have a couple jigsaw games and Minecraft for Windows 10)

Also Used:
Gamejolt, Origin and GOG
ATLauncher, FTB Launcher, Technic Launcher, Pixelmon Launcher and Mojang's Launcher for Minecraft.
Nox for Android games

GOG, Uplay, Origin, Steam, Nexon, Battle.net
Something like that.

Steam and Battle.net if I want to buy something.
GOG, Uplay and Epic for free games.

Pretty much all of them (usually Steam for everything that is on Steam and the rest only for games that are not on Steam).

I use primarily Steam. Sometimes, I reluctantly download another launcher if a game that interests me is offered for free, but I never buy games that don't activate on Steam.

To this day, I've only ever used GoG's Galaxy (they sometimes offer games for free), UPlay (required for Ass Creed) and Kongregate's Kartridge (because I like Kongregate the website).

Steam mainly. Uplay if playing a Ubi game on Steam that requires it. Origin very rarely(probably not again until Dragon Age 4 is out and cheap). Rockstars garbage launcher for gta and whenever rdr2 comes out. Not interested in having 82374682743 clients, so, I'll wait for the store wars to end, and hope that Valve wins. Otherwise, I'll probably just buy games used for ps4, so the publishers that are forcing other shitty clients don't get my money.

Have we ascertained why it's highly important yet?

I find that the gamelauncher program named "playnite" is pretty good.
It lets you add games from steam, twitch, GOG, uplay and others and creates an own library.
that way you can launch all your games from just one launcher.
Its pretty nice.

I have everything but Bethesda launcher because of freebies but usually only purchase off Steam. Opening an extra app to launch a video game is no big deal to me though and I don't think it should be to anyone besides maybe the principle of it. I've stuck to almost always purchasing on Steam not because I care about extra launchers, but because I like to achievement hunt and brandish my internet peen with a slightly above average game library and Steam level ¯\(ツ)/¯

After I get done binging the first two Mass Effect games I'll probably be caving in and buying ME3 and Andromeda off Origin instead of torrenting them this time though. I would have never bought something off Origin before because EA BAD but honestly if I really want to play the games it shouldn't matter what launcher they're on. It's not a big deal

Only Steam, except my loved Crysis 3 on Origin. In others launchers... all free... :)

mostly just steam tho i do have gog for when i want to play CDprojekt Red games ( figure it give them the most supprt since its their platform) and i have origin that i mostly never touch and recently installed epic launcher for a couple free ones.

I'm mostly using Steam, Uplay lately a bit, Origin very rarely....I haven't played a single game with the Epic Launcher yet, but I have it installed for Unreal Engine and I don't use GOG besides when I played Shadow Warrior 2.

Battle.net...yeah, I really don't care about that, maybe when I play the free Destiny 2 in the future.

Steam
Uplay
Battle.net
Origin
GOG Galaxy

I have uPlay, Origin, GOG, Steam, and battle.net. Oh and Rockstar's client which I've only used like once.

Steam for most of my games
Origin for Sims 2-3 and Bejeweled 3 (although I haven't logged into it in ages)
Glyph for Trove

Steam, Origin, UPlay, GOG Galaxy, Battle.net, and Epic Games Launcher. And, for some reason, I haven't uninstalled Desura, yet. XD

Currently have/use these along side Steam:

• Uplay, since that was necessary to play Ubisoft games even from Steam and they've since given some decent titles away for free
• Epic Games, since they gave away two games from my wishlist
• Battle.net, for Overwatch only

I haven't uninstalled any of the launchers ever since first getting them, that would feel like a hassle. Don't really want more but I might eventually cave if suitable free stuff is given out.

The only launchers I use are Steam, Itch.io, Jolt and Nexon( for Mabinogi ).

Other than Steam I have GOG Galaxy, Origin and Uplay installed, but I hardly ever use them.

You forgot Battle.net and Twitch

Steam, to play main games
GOG, to play games which aren't on Steam
Others are for free games only

"This is a highly important poll."
one of the answers: I love potatoes.
