Thats interesting..I knew that Nam was NGH-001...so I went and checked all my NGCD games that I also have on AES...and all the numbers coincide with each other.
For instance RBFFS is NGCD-2230 and on AES its NGH-2230.
So it looks like they just put them in the exact same orders as the AES carts. I doubt that they were actually released in that order...but its possible.
