Usually Day One editions have some perk with it.For example, FF Type-0 had FF15 demo with it, and supposedely only the Day One Edition had it.But I have never seen any other type of edition or version out there, so in my honest opinion is just to make the game look fancier.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
