Add the contents of a CIB video game to their respective listings

Complete in Box means it contains everything it had when opened originally but many people don't know what is in the original packaging. Lots of times there are inserts, cards, or extra contents missing and a spot to add that would be nice. For instance the Doom 64 classic edition Xbox Limited Run has to have all of the following in order to be considered complete:

Doom 64 Classic Edition includes:

• Physical Copy of DOOM 64 for Xbox One
• Premium Foil Embossed Classic Edition Box
• DOOM 64 Booklet with Developer Interviews
• Commemorative (non-functioning) Metal Retro Cartridge
• Reversible 18" x 24" Poster
