I liked it, more or less, although I think it could have ended a bit earlier. I felt when you
finally met the long lost exgirlfriend, that, OH WHAT A SURPRISE IS STILL ALIVE
, would have been a good point to bring it to an end. after that it felt like the story was more like.. slapped on the end.
what really bugged me:
xp for taking out enemies. i literally cleaned levels just to get xp. fail gameplay.
xp for hacking terminals: i even hacked my own pc to get xp for it. not that bad as the one above, though.
energy system: pretty weird that only the last slot recharges. and i dont want to eat a power bar so i can punch someone in the face. i understand that this was done so you cant just melee all day long, but some compromise would have been neat.
augmentation system: what i really loved about dx1 was that very last aug you got, that either buffed all augs or made them energy saving, iirc. was a very nice touch, i was hoping for something like this in here, too. i was disappointed.
ending:
click button to see different endings? meh. it should have been based on actions, not on what button you press.
in general, i'd give it a 8.5/10, and would say in some regards it's better than the original, in others worse.
