If you quit SystemShock remake without finishing, why did you quit?

Steam says only 16.5% players have the achievement you get when you finish the game. (And 6.8% have the achievement for beating Shodan). I have both achievements and I have opinions as to why most players don't. But I'd like direct info from players.

If you are one of the seemingly 83.5% who bailed out, what were your reasons?
