There's one other factor to consider.
Any story that doesn't have a consistent narrative for all users is not valid. In some cases, the gameplay and the narrative are entirely separate parts of the game, so the narrative never branches.
Per this policy, if there is no narrative or a branching narrative, it's invalid and we don't need to discuss it. Yet in the rare cases of a non-branching narrative, discussion is necessary, which is why each game needs to be discussed individually.
