I used to play games like Ultima7 and now I play Oblivion and an interesting thing i like about those two games is that NPCs literally wake up in the morning, have breakfast, go to their shop, open it up and do their business, take a break for lunch, close shop in the evening and then go to bed at night, (at which time it would be easy to break in their shop and steal stuff).
When using cheats in Ultima it was possible to see the schedules for the NPCS.
08:00 wake up
09:00 go to work
12:00 eat lunch
19:00 go home
20:00 eat dinner
I pictured if in Sindome some NPCs would close shop and head down to Drone for drinks in the evening then disperse to ther homes and leave shops guarded by autocannons or dogs or something.
Anyways, just a thought.
