Steam is pretty much all-in-one for anything you would ever need for PC gaming.
This.
I have only thought of steam as bloatware.. but that changed since I got my physical copy of warband that turned out to be a steam version.
I was quite unhappy about it but went along since I wanted the game anyway.
On Steam back then there were what, shop, chat and games to play?
I mean, look at how much it has progressed during those years, like since I have bought Warband itself, which was in july 2010.
And that was still great for it's time, predating all this useless junk like Origin etc which are the real useless, forced bloatware crap.
Needless to say my views have changed completely and Steam is mandatory for me now.
