Just finished took me exactly 30h+ the 20h of my first playthrough that I scrapped. I still love it, though I doubt I will start another playthrough soon.
I hate that you are forced to work with the maniac Sophia and that you are forced to destroy Edgewater which doesn't seem to benefit the board at all. I played both sides until Tartarus which was quite fun and ended up as the true ruler of the colony with the director as a front.
Forced how? I did the Board ending and never destroyed Edgewater. In fact they got a very prosperous ending slide. The game is more reactive than people think.
