I bought Dark Souls 3 Day One Edition, and saw that it came with Dark Souls "full game". I'm asking from anyone that knows for certain that this DS3 Day One Edition comes with the Artorias of the Abyss expansion. I want to buy the DLC, but am unsure if I already have it in the game that came with DS3.
If you do indeed have the Day One Edition, then you don't have any DLC apart from maybe the stuff included with the Day One Edition like the soundtrack. If you want the DLC for DS3, you'll have to buy them separately or get The Fire Fades Edition (which is essentially the GOTY version with all the DLC). I'm not sure about the 'Artorias of the Abyss expansion'. I'm not overly savvy with DS myself.
