Steam used to be an additional thing you had to install/run in order to play the game you already bought on DVD from the local game store. Now it's a service you use to buy games (often at ridiculously low prices) and automatically download them. That's what changed popular opinion of Steam.
Sorry, but it still is an additional thing you have to use/run/install when you buy a boxed game from a B&M store. I found this out only after buying one such game. This is the reason I cracked it and then vowed to never buy another one that does.
