Finished the game. It's still good, but there are caveats, which I will hide behind a spoiler tag.
Whoever at Squenix was responsible for releasing the game as it is deserves to get punched.
No, this isn't a comment on technical quality. It isn't a comment about the writing or gameplay, both of which are at least on par with Human Revolution. It is purely a comment on the ending, which doesn't exist. The game doesn't end so much as it stops; there's no real epilogue or denouement to be had here. Once the final mission is done, all we get is a short dialogue scene, a video of Eliza Cassan spin-doctoring whatever you did. There are indications that what DXMD delivers is merely the first third of the original outline before Squenix ordered Eidos to squeeze more game out of this.
With that out of the way, I should probably also comment on the story. A big deal was made in runup to this release about the augmented as a metaphor for minorities (specifically, black minorities in the US), and that whole thing just. does. not. work.
The idea of a "mechanical apartheid" kinda works. The opening scene in Prague, where you're subject to intense law enforcement scrutiny just because you're an aug, works. The general concept of a massive distrust towards the augmented works too (the incident at the end of DXHR being responsible for a lot of very visible deaths, after all), but I am not sure just how exactly a bunch of scaffolding is supposed to stop a rampaging hanzer in a subway station.
Oh, and about the Microtransactions in singleplayer: There's no reason to ever use them. The game feeds you credits and XP at such a rate that there's really no need to ever buy yourself praxis.
