I recently came across Should you ever deploy your blank at a position other than an edge in Epigo?, which seems like a decent question. However, it lacks a game tag. As best I can tell, it had one at one point, which was automatically purged from the site (see Are tags mysteriously disappearing?).
I'd like to be helpful and add the tag back in, then add a tag wiki so that it doesn't get purged again. But the thing is, I have no clue what game it is. Other questions lacking a game tag usually have the name of the game in the title or the body of the question, but not this one.
While I hope that someone can identify this game, I'd also like to ask: what do you do in general if you come across an old question that no longer has any information about the game?
Also, do we do anything different with closed questions? I've come across Big or small team members in Heroclix?, which also lacks a game tag or any identifying information, but is closed and unlikely to be reoponed. Do we just leave these questions or do something else?
I suppose I could create an identify-this-game question about these games, but that seems a bit overkill.
