My apologies if this has already been discussed (I tried searching the thread), but are there any theories as to how your choices regarding Ian's book will impact the story? It's more or less the only choices that currently aren't affecting the game in any way, as far as I can tell.
Is it possible that you're actually making choices for Ian's own story in the future? That choosing your protagonist and antogonist type, deciding if it will be about revenge/treason/doom and so on is in some way deciding parts of the character's path further on in the game? Maybe it's a bit far fetched, buy I think that would be funny.
