I know, I know, it's not in any of the books yet. But we might as well get a start.

So, I'm cataloging my collection, and I've gone through all my Xbox discs (only about 20 or so right now, including demos). The problem I'm seeing is that there's no consistent stock number to refer to. Here's what I see:

* Each disc has its own number (except for the ones that have no number).
* Each box has its own number, not related to the disc number.
* The UPC has no correlation to either of these numbers.
* Third-party releases don't follow any set numbering system at all, unless...
* ...they feel like roughly copying Microsoft's nonexistent system. x_x

Don't know if anyone else has looked into this, but it's frustrating. So far, I've been cataloging by the number on each actual disc to keep it somewhat consistent. But since some discs don't have stock numbers on them, I've had to use the box number instead.

Suggestions?
