I denied the Metal Gear edits because the info as presented in the database exists as an item. Your edits, if approved, would have changed that existing item into a different one. So the edits were rejected.
Metal Gear Solid Legacy Collection with artbook (in db) vs without artbook (what you tried to enter).
For the DB game (it is not titled DBZ), the one you did edits for was previously run through as a dupe. So the edits were rejected because they didn't apply to anything anymore. Now that the game is re-added, all if fine, although I do not like "first print" in the name. Is there no other physical difference on the case or disc to differentiate from the other version?
