The amount of Steam bashing and unadulterated ignorance flying around on these forums sometimes is simply ridiculous.. people are freaking out over Steam? It uses all of 20mb of system RAM to stay open, jees.
You can even disable almost all of it's features and go bare bones down to 15mb of system RAM. You can right click a friend and instantly join their game, this is only a good thing for Civ.
Just where do you disable all of its features? It's not in any settings menu that I'm aware of.
And to the above post, the Steam UI update was the first mandatory Steam update in I believe three years. You can turn off your game updates too, or download them elsewhere away from Steam and install them manually if you REALLY don't want Steam on the internet.
If you know how to disable Steam client updates, I would be most interested in the process of doing so. I know you can disable automatic game updates, but are we still able to play the game without downloading the update in online mode?
My understanding is that to download an update on another computer is basically to copy all the files that were modified. Not exactly an option unless you have a list of all the files changed or you're willing to copy the entire installation, and either way you're in trouble if the executable was updated (Steam would have to reauthenticate as far as I'm aware).
