Dagmar
Defender of the Bunnies of Skyrim
That's not a Steam feature. It's a feature of the game. The undeniable fact remains that Steam offers no means to disable DLC and many games (probably most if not all games that don't allow modification by users) don't have a built in option to disable DLC.I gave two answers.
1) to disable the DLC's do this:
if you launch Skyrim, and click on "Game Data" (on the small, first menu screen), you have the option to disable the DLC.
I already explained why that's a total non-solution. It won't work for Borderlands 2 or most other games. The bottom line is that Steam doesn't allow you to disable DLC. It's an extremely rigid and inflexible in this regard and therefore Sean_'s observation of this fact is completely valid and your counterargument is irrelevant as it has nothing to do with how Steam functions.This works perfectly for me. If it doesnt work for you, than just use steam in "offline mode".. and you can google how to do that, I'm not explaining anything else as it seems to be a waste of time anyway.
