Currently there is a tag avalon-hill, but no general tag for wargaming.
Also, AH was only one of hundreds, maybe a thousand or more, companies publishing board wargames.
Could somebody add a tag for "wargaming"/"wargames". and perhaps "spi" at least (they were probably bigger than AH).
Edit: and also a tag "maps" or "wargame-maps" would be nice.
More: needed for this question.
