//Possible spoilers about the dlc;
Seems to be a clear rip out from the original game and make dlc to cash in, as it takes place before the end of the original, you know what's going on. Sure, it's a story being told and he's constantly asking about reed but you know what happens. To me it didn't have the mystique or development as before.
Regardless, it didn't stop me playing it and finishing it, 9.5hrs on steam, I'm sure a fair whack of it was alt tabbed or afk (I played stealth and explored everything). There's a lot of places where you need to carry boxes around to stack and get around if you dont' have the jump height aug. Even then some places might even need 1 box.
Tbh, if you haven't played any DXHR yet, play it, at the harbour after the "event" happens, play the DLC, the back to the original game. For me, that would simply extent the life of the game, despite there being some aug differntial from the dlc to original.

Eidos Montreal marketing said:
“The Missing Link is about a fresh start for Adam. New augs, new weapons, new situation as the underdog."
Either that was clever marketing or just poorly choiced words, there are no new augs, or weapons. That's not how you explain that, "you have to retrain all the augs you want again". Old augs, old weapons re-used.
He does say fresh start but meh, semantics.
