What Custom Categories Do You use to set apart from other's builds?

[Gaming.Zone]

Hey all,

I have been using Launch Box for awhile now.  I recently backed up my old build and started a fresh install that I plan on importing or moving games back when I complete.

What I am trying to do with this build is organize and configure platforms that seems to bucket them better.  Currently I am looking at adding defunct and un-emulated systems to the list (hiding all the games for when in Big Box) in the hopes I am ready to move to this if they ever release.   I am coming at this more as an archivist point of view then a gamer.

What I am looking for from other users is what obscure Categories they have created that are outside the normal (Arcade, Computers, Consoles, Handhelds) What reason did you create the category for?

I see some users have put in some categories like comics and magazines.  (Which might be cool as reference material of a small collection for Nostalgia reasons - Like 80's G.I. Joe or Transformers as well as Nintendo Power).

I am thinking of creating sub categories under the main ones to separate Dedicated consoles out from cartridge or disc based systems.  Also I was thinking of a separate category for eshops outside of their platforms.

Please share your ideas. 

Thanks all.

Only other category I did was I group my platforms by manufacturer where possible. So in my Consoles category I have a category for Nintendo, Sony, Sega, etc then the platforms go in the correct subcategory. I have a build that has a lot more nested information for easier navigation in Big Box (Without the need to use the filter menu) but I don't know that it's always needed to do that.
