I mean, I know that it is crazy late in the PSX's lifespan, and like any other system it will have some rare gems that will come out (or came out) near the end of it's lifespan. But, I'm kind of doubting Gameday here folks... remember, first and foremost, it's a sports game, those don't hold value at all. Second of all, the Gameday name and 989 Sports has practically no cache with gamers these days anyways. Still, I guess that if the print run is low enough...
Edit: As an aside, is Sky Gunner for PS2 considered rare or hard-to-find? Thanks.
