As I understand it, the Living Word in the traditional form of play, doesn't require a bad roll for the GM to introduce consequences.
In many indie games, it appears that the Living part of the world sometimes requires a mechanic to drive such consequences. i.e. for the GM to author stuff in.
EDIT: Therefore, sometimes the mechanic (the results of the dice) may not allow for consequences, which you normally would expect in a Living World. Ofcourse, in defense of the mechanic, one could always create reasons/explanations why consequence did not come to exist.
Well it depends on what you mean. A living world would be one in which I'd expect consequences for actions. And that things can take place without the PCs' direct involvement.
Some games may have consequences on a roll, but I don't think that those games ONLY allow for consequences related to a roll.
Did you have a specific game in mind?
