> ok stupid question what does o,m,c,i mean
I have a key on the top of the document, but I can expand on that here:
O: Outer box. A box that was designed to hold the game and some other extra(s). Sometimes it's a small box, like the one for Samus Returns on 3DS that only had the game and CD, other times you'll get the Ni no Kuni 2 box which had lots of things. In all cases, the extras are not included. Box inserts may be present.
M: Manual. Pretty basic.
C: Caseart. Used mostly for later portable games, this is the artwork that belongs in the case. Cases themselves may be available on a first come, first served basis.
I: Inserts. I admittingly wasn't too good on marking these, but this means the little extras that were in the case- registration cards, Club Nintendo/Square Enix loyalty codes, etc.
B: Box. This is the retail box which contained the game. Genesis cases fall into this category, as I do not separate the artwork from the case.
S: Slipcover. Most commonly, this is an O-sleeve that goes over the game. Compare this to the cardboard sleeve you also see on a lot of special DVDs. In other cases, it may be a partial wraparound, like the slip from P4A ultimate with the Teddy punching item.
To also stem off the question, the next column is for my use. It tells me if something is in storage or if I have multiple copies.
