It's all good, hope you had a fun vacation! Glad to have you back :D
Sounds like a thorough way to categorise them, though we do already have categories for the respective groups.
I take it we are doing similar with the weapons pages as well? Such coming out in a format like:
Weapons > The Last of Us weapons > Left Behind weapons > Part II weapons
With each weapon them being categorised into their respective type (melee, pistol, long-gun etc)?
Side note: We could suggest these in the forums if you'd like?
