How about this?
-We can do the perpetual story , with a few set rules and adding some as we find need for it.
-We also set up some achievements that are awarded for certain feats of gameplay so people feel accomplished.
-Players play as one character at a time.
-We create a few threads that are "locations" in the in-game universe, and the action happens on these stages.
-We develop some factions, that have their own private threads for additional discussion.
-As we go, we create encyclopedias to describe the items, locations, factions and species players have encountered, which will facilitate continuity.
