Are compilations allowed?

While I've noticed that titles such as the Sega Genesis Collection are allowed, I thought I'd check to see the rules on adding compilations. You see I have a few compilations on the Commodore Amiga and ZX Spectrum that are not on the Giant Bomb database and I thought it best I ask before trying to add them. They're the standard kind of compilation you'd see on computers back in the day. One box, multiple games on several tapes/disks.

So, what are the rules in regards to this sort of thing?

Compilations are only allowed if the games are on a single piece of media be it a disk, CD, tape, whatever. If it is just a package with the individual games on their own media it does not.
