Sounds like a lot of messing around. The online Steam system has a lot of pros, but this is why I also love to just stick a disc into a console and play it.
And that reminds me, I bought Super Meat Boy on sale on Steam a week or two ago, and haven't installed or played it yet. Totally forgot.
Except you can't even do that on the new consoles. Buy a new game, stick it in, does it ever just play? Not in my experience, immediate updates/download and wait. Still, an easier system that Cyclops scenario, but it's not just so simple as it used to be.
If you are a PC gamer, I can't imagine a single reason to buy a physical disc anymore. It's sooo much simpler to just keep it in your steam account and then download/install when you want to play.
I don't know about the latest gen of consoles, but on XBOX 360, yeah I just stick in a disc and play it. Simple as ever. Installing and/or updating the game are optional, not mandatory (probably different if you did online gaming, but I've never once done that on PC or console).
Downloading and installing big games on my internet would take too long and use up far too much of my monthly bandwidth, which isn't worth it to me for gaming, which is one reason I wouldn't game on a PC. Physical copies are little more than shelf advertisements these days.
Both have their pros and cons, which will be different for everyone. That's why we have both!
