I really, really, enjoyed the first part of this- I found it great, and a fab mix for skill sets- both investigation and combat. But- the end was majorly overly complicated, and hard to get into the mindset needed. It was interesting, but came as a shock from the rest of the game.
Its been years since I did a degree in philosophy, but it made me really think if the ideas went together, and I'm not sure I agree they do. Its very subjective, and unlikely to get a concise response.
I would happily run this, but deffo build in time for a very, very long discussion between the players at the end. It will certainly increase the time taken to complete.
