Haha. I actually stopped my second play-through because of this news. I'm going to go back the BIG decision and start from there. I lost my perfect ending save file and need to recreate it! I was going to go back and make different choices, but I was too happy with the choices I made, and decided I don't like the other way, lol. Luckily I didn't get far on the DLC either, so I have that all new to experience. About half way through Heart of Stone.
I've about 180 hours in total between the original and the DLC. I only finished the main story last year and Ive been working through the DLC since. And that's not even covering every quest. There were a few I failed for various reasons, some I missed and others that are still pending.
All said though.. I cannot wait to see what the series X version looks like. I'm think it will blow most newer games out of the water.
