I use steam and origins. I use origins mostly for star wars and the sims and steam most of my friends play so i use that to be with them.
I use Steam for Dota2, CS : GO and a couple of other fun games when life gets boring with WoW but ultimately WoW draws me back :D
I used to use Steam, but I find that if you can't pirate it you don't need it. I'm just that kinda guy. *Insert Piracy by Nyhm here*
Thanks for all your answers, we will be picking winners soon :)
I do, I use Steam. I use Steam because they offer a lot of great deals on games and also because frankly, most games require it.
