Rob, thanks for your kind comment - I read your excellent proposal and agree the ideas could be combined. So I added a pointer to yours into the above text. Just thinking - Did you ever watch the "I Robot" movie? One could even record "pseudo conversations" like the holographic one between Dr. Lanning and Spooner (after Lanning's death). One could thus create something between a multiple-choice "conversation" and a simple adventure game for the survivors... ok maybe that's over the top...maybe not!
