True indeed. I was only curious really about the Ys game. I had not seen that before so I figured that I would ask those who might have seen it before. Thanks for all the info though!
I forgot to mention: look at the second auction you linked to...
Notice something about the games? THEY ARE IN EMPTY CASES. The manuals were separate.
This is how folks who purchased DUO new received the items.
NOW LOOK AT FIRST AUCTION: clearly that is the original version of Ys I & II, for RETAIL on shelves in stores, and would have been sold in a cardboard box with a UPC.
Yep, I clearly remember this, all of the manuals were separate when you opened the box. Ninja Spirit didn't even come with a case, just a huey, so that manual was definitely loose. Oh, and I think you got Bonk's Adventure and Revenge manuals along with Gate of Thunder, too iirc. I think since I've had it I've always just put the GoT manual with the 4-in-1 disc jewel case.
