literally just completed it too, 20hrs total according to steam.
full stealth, didnt kill anyone (tho didnt get the pacifist achivement wtf??), hacked everything, almost had all the augs bar about 3, read pretty much everything (a lot of it is spam anyway) , 28achievements, did every side mission i came across, spoke to most people, all endings and did the bonus dlc to boot....
no idea how people are taking so long, it is a pretty linear game to be honest bar the few side missions i clearly missed but this is too be expected unless your reading exactly where they are beforehand.
my thoughts:
great game, ending is a bit wolly (all of um) but good enough, final boss battle was ok - not to hard but entertaining...dont really mind the battles as iv said earlier not sure why people moan so much about them asides from the difficulty spike.
interesting to see what dlc comes next and if its worth exploring. will probs play again within a year and do all guns blazing mode and try and track down the final side missions.
love the cut scenes in the game too, all of them were top class entertainment so whoever did those really needs a pat on the back.
35 hours for my first play through and currently on 25 hours for my second play through. You guys must seriously be rushing
did you read everything and go exploring, i'm struggling to understand why people completed it so quickly, i read all the e-books and e-mails on computers that in itself is quite time consuming.
no I think most people are playing it normally, not like some sort of religious experience. reading everything really doesnt take that long if your a competant reader, and a lot of it especially terminals are spam emails , or repeated chain emails across different pcs.
and exploring? i jumped everywhere , moved everything, went down every vent i found etc etc....
like i said some people are just treating it like a religious experience a bit too much.
