That's pretty much the idea I had. I was thinking that a good way we could make ourselves want to RP, but not screech to a halt if not everyone can participate at some point, would be to have the RP center around our group of characters just living their lives in a city TBD, assuming it's TES (Daggerfall has my vote.) If most of us are active and around, our characters all meet at a tavern or go on some adventure that we won't spend 80% of the total time planning, and if only a handful are active at some point, they can pursue their own stories/character development on a smaller level, just among them, writing off the others' absence in world in any number of ways and just carrying on.
