Yesterday, Steve V marked a series of questions with after-the-plot. A good tag, but there was a short discussion in chat as to whether it should be renamed to something like post-game, which is a more common monicker for gameplay after the "resolution of the main plot".
But post-game specifically refers to gameplay, not story. You don't call the ending or the spin-off books "post-game". That is one scenario where a classification of "after the plot" would be valid but not "post-game".
All 6 questions with the tag, as far as I can tell, are about post-game activity and not story. And I think there have been questions about endings and such, which do not have this tag. I'm thus not sure that we necessarily need a separate tag to differentiate story/plot questions that occur after the main story versus during the normal course.
In chat, Powerlord mentioned the idea of epilogue. For the most part, epilogue tends to much more often relate to just the plot elements, and so it may be a good option if we do need a separate tag for post-resolution story that won't be frequently confused with post-game.
This session of the Dark Assembly is now in order. Aye or nay?
