Firstly I don't fully agree with the genre definition here. Yes you can say it RPG to the same extent as you can say that DOOM is. It actually is much closer to the quest games of late 90s/early 2000s. That said it does not take anything away from the game. The game itself is absolute masterpiece. From now on I have a new standard for character, dialog, narrative design for myself. And it will be very hard to surpass it.
