Metaphysics in video games has always been something that has interested me (36 Lessons of Vivec is amazing). I am not entirely sure why, but it is most likely the slight insight into the writer's mind and how their world-view(s) influence the story of the game that makes the topic so interesting for me. I was even more excited about P:E when I found out about the part that souls play in the world, and I am interested in discovering how they are explained in the story in more detail.
So my question is, how do you feel about the inclusion of metaphysical topics in video games (and P:E in particular)? Do you think it strengthens the story and makes you consider things you have never thought of before? Or that it makes things overly complicated (which it can do at times) and only serves to confuse and make things even more obscure?
Also, I understand this subject has the potential to lean toward more religious topics, so try to keep it civil... There is no need to make this something it isn't, so just to say it again, this is about metaphysics IN GAMES/FICTIONAL WORLDS.
