On JDCorley's point of generating content. Heres an idea... kind of out there. Would require some dedication to initially code up and write up, but once it is done it could be a good source of RP and a generation of resources (mainly Nuyen) that would require minimum staff involvement.
Essentially everyone would have access to a once a week (to avoid abusing the system) pre-generated Run System. First they would decide how big their team is (up to a max of 5 and even allow for a team of one), the code would then choose a random story that has been pre-generated by staff. It then plays out like a choose your own adventure. You get the set pose, allow everyone to pose then the party leader hits the next button. The next pose comes out. They continue on with the story until they hit either a challenge or a fork, each with an accompanied pre-generated pose. If its a challenge they have to pass a roll or suffer a failure. (could be a simple as someone is injured, they fail part of the mission, or they fail the entire mission) A fork changes the outcome of the run or sends the run into a new tangent. (This could allow for a pregenerated system to have some extra life as not all runs will be the same) At the end of the run, depending on if specific objectives were met, rolls were passed, and what forks were chosen, the team gets a Nuyen award or maybe a favor or item they can use in future runs. Again these pre-generated runs would be limited to probably once a week. Maybe once every two weeks. You don't want everyone to just rely on this system. You still want staff runs and PRP to be an avenue.
This allows for a system that runs without any staff involvement except for its initial placement. It allows for groups to RP action based scenes without the need for an experienced storyteller or active staffer, and even allows for those lone wolf types to earn some money and develop a side story they can tell to their friends.
It allows the game to feel alive. You could code up a secondary system that could tie run results into a News Broadcast Board where some corporate mouth piece comes up with an excuse for a recent run and your players can smirk knowing theyre talking about them.
You can also make it so that your staff initiation for the game is they have to make a pre-gen Run, or allow players to submit pre-gun runs for a lil XP.
