I noticed many of the Senran Kagura chartags are often accompanied by their respective debut game copytags even when there's nothing else pertaining to the game in question. As I understand it, this is not how we should be using copytags. It probably made sense in the past when the games were still new and the characters were only in that game, but most of them are part of the regular roster now and they're still being tagged this way I did it too, but only because I tend to follow how tags are currently used for the most part unless it's obviously wrong.
I'm actually convinced it is wrong, but I know some copyrights have a few exceptions for whatever reason and I want to make sure my thinking is correct before making any sweeping changes.
TLDR: Do the Senran Kagura posts tend to have too many copytags?
