As for games like Fallout / Soul Reaver, that I am fan of, I know almost everything including the "apocrypha" - deleted material.
Like fact that there was a guy intended who rivalved with you to become the Chosen One and failed, so he turned evil. His name would be Kaga. There are dialogues for him coded, but he's not in game.
There were also deleted materials, accessible through a special patch (which I never downloaded, but heard of it) - The Abbey, the cave with Holy Hand Grenade (most powerful throwing weapon) and some other unfinished vault.
Also, it's pariah dog, not pirra, heh. Pariahs are the lowest caste of people in hunduism castes, the "unclean".
Best guys ever in F2 were the hubologists. They wanted to see their god so they were building a space shuttle to go to him Laughing Actually, they beliefs made some sense. Except when I joined them, the "good" karate master (Dragon, I guess) in San Francisco hated me. <_< ("go away, sheep of the hub")
Also, karate tournament in San Francisco is best way to get experience (8000 exp for finishing both trainings, for Lo Pan and for Dragon), and you simply can take psycho + buffout combo before it, lol.
Best random encounter? The bridge keeper. Smile
