chrissie: "A 3rd game, in my mind, would have to focus more on Kate Walker.... Also perhaps Hans on finding what he wanted may like to stay or now move on?"
Honestly, Hans wasn't very likeable.
Sokal built Oscar up as very human but
Hans set up Oscar to be sacrificed for his own ends without a thought.
I can't really see following Hans any further.
Come to think of it, Kate wasn't exactly guilt-free there either.
It would be more interesting if Sokal pursued the question of what is human?
Can an automaton (in his world) be said to possess, for want of a better word, a soul?
I'm sure Isaac Asimov has already answered that but he didn't live in Syberia.
