Which path has the most content?
Because I remember playing this game several months back and the game ends up in the exact same spot it did back then. I chose to stay, had a crushing victory against Hassan and chose to marry Marion. There's little to it after that.

That's currently where that route ends yeah.
The most content is probably along the route where you decide to marry Varga, or refuse to marry either.
Then there is also a lot of content for leaving with Kate and either deciding to join the mercenaries, or starting the Mage route. Both those paths currently have some of the longest running routes.
