How important, do you feel, is it for backdrops to have some kind of activity going on even if the player isn't moving. I see in things like Space Quest (4 through 6 particularly) that there is always *something* active - neon lights, people walking past, fans spinning - ans I was wondering how much importance you folk placed on making sure something was going on. I seem to have had a mad quest to shoehorn any kind of movement I can into it lately, and was wondering if there were any precedents for not having to put quite so much in.
