I am not an expert on how Steam works, so I need someones help.
I don't have a disc drive in my system because I am a cheapo and just figured I would buy every game on steam digitally. I was going to invest in Black Ops 2 and then noticed that I can get the retail disc version of it on amazon for $45 opposed to the $60 on steam. Since Black Ops 2 can be activated on steam does that mean I can buy the disc version and just activate the cd-key on steam and install it from steam?
Reason I ask is because I have never bought a retail PC game
