There is a demo available on steam that you can play. Just looking at the character creator and playing it for aproxamatly 30 min I can say with some deal of certanty that you can easily get 3 playthroughs of this game easily. Each character archtype plays differently, and there is a belief system that rewards you for playing in acordance with that belief system, for example a rationalist will try to rationalize everything with logic. Plus while everything seems to be morally bleak and grey, there does seem to be some good like paths and some obviously evil and demented paths through the game. Hope this helps.
