Should a game lose point for adding auxillary content that isn't good?

[Millenium]

If it's released as DLC for a game you already have? No.
If it's included with the original game? Yes. (For example, I would count Multiplayer for God of War: Ascension as a included feature because it's included with the base game, sure it's optional to play, but it's part of the original package).
