Although SE in general considers tags to be equal, we have atleast 2 tags that I know of -
achievements - that are only valid when paired with another tag for a particular game or series.
However, the code for suggesting related links doesn't take this into account. So for e.g., if I am viewing a question on Diablo 3 lore (tagged
story) then it may suggest story questions from other game universes like ME & Skyrim.
This is kind of a unique feature request based on gaming.SE's domain, but I think it'd work better if
- 'Related' links gave more importance to having other tags in common (this doesn't need to be gaming.SE specific)
- Should not allow users to tag a question with only story or achievements (no idea if there are such posts or how to search for them)
