I've noticed that the Crash_Bandicoot_(series) tag also comes with the tags Sony_Interactive_Entertainment, Sony_Corporation and Naughty_Dog tags attached to it.

This might have been accurate ten years ago, but these companies currently do neither own the Crash Bandicoot franchise, nor develop it. Crash Bandicoot is currently owned by Activision and is currently developed by either Beenox or Vicarious Visions.

While I think that adding an activision, vicarious visions or beenox tag might cause similar problems in the future, I think remove the sony_interactive, sony_corporation and naughty_dog tag from the Crash_Bandicoot_(series) tag might help inaccurate searches.

I imagine that most people who would search for Naughty_dog would probably do so with one of their more modern games in mind, and having that tag flooded with Crash Bandicoot content despite that series having nothing to do with them might make the tag useless.

Might be best to change it to an activision implication instead, perhaps. Also, naughty dog is what implies sony entertainment, which in itself implies sony corporation, just to clarify.

Might tweak with this a bit, though I will note that moderness doesn't really matter when it comes to some copyright (see the rareware tag, for example, filled with content of franchises that haven't really been seen in the modern gaming era for the most part)
