I hate DLC. Its too small. I don't like a little chunk of a game at a time, I like the whole thing in one big fat sexy play through. Thats why I have done 3+ full BG plays, thats BG, TotSC, BGII and ToB - seamless.
I really feel like im not getting the full experince if I don't have the DLC. I wait until I have all that makes sense before I play.
So, nice big chunky expansions = GOOD. Small tiny unfullfilling empty DLC = BAD.
Giving all the DLC away for free on PC release of a console game = Im okay with that, that is one way to make the pc version a bit better than a cheap port. Im just scared all the second rung down games will drop PC altogether, Gears 2 style. If they arn't making money on the DLC for PC then there is even LESS reason to develop for the superior platform.
To sum up, I would reinstall a game for an expansion, not for DLC.
