This problem really gets to the core of the game design.
I think the only resolution for this is really a huge effort to make that whole 'massive, faceless entity' thing an actuality game wise. So we get various hints game wise that things are moving behind the shiny corporate facade of Gold, and it would be stupid if things were any more 'obvious', but at the same time we need to make being a corpie a part of the massive entity, need to make them feel *membership* in a community like Red residents sort of get.
Since there are fewer people topside it's would seem more likely that 'membership' in the corporate world would be a lot more communal and closely knit than Red.
But again, to get that feeling of membership across would require tons of GM puppeting which clearly is not a feasible thing. And since we don't have enough players to make the whole 'large Corp.' idea even close to a reality, there has to be more done in the way of 'cushioning'. 'Padding' in the corporate world. What I'm getting at is:
More automated activity.
A corp. is a machine. So automated stuff wouldn't be unrealistic. Automated activity that could be followed by players, that wouldn't necessarily involve tons complicated code in the interaction between NPCs and players, but keep them a part of 'bigger things'. So instead of idling aimlessly and making fun of Red residents over SIC they could actually be kept as busy as corpies are supposed to be.
Plus, even though Judges, as I've read, were once a source of RP topside, and that would have been exciting and violent and whatnot, it really doesn't contribute to the overall vibe of the game, the 'corpie atmosphere', as it were. Violence and crooked cop based action should happen only at the *margins* of the whole. It can't be allowed to form the whole focus of 'excitement' or activity in general on corporate levels. That would suck.
Corpie players should be completely immersed as members of the machine. Things should happen automatically that *imply* a huge corporate structure at work behind the scenes, so that the core operations would happen even without GM intervention.
In short, we can't ever expect GMs and players to create Gold and topside levels into a working, believable, gargantuan machine. There's just too much to be done, and I fear that any attempts to do so will just result in failure and loss of morale. I'm committed to this game and I want to see it expand because I believe it has great potential, but to succeed more has to be done that would make Red and Gold and Green *really* different experiences.
I've posted a bunch of ideas to try and help make this a reality and to try and consider some issues surrounding the problem of 'automation vs. player action' balancing and flexibility, and I think automation could contribute and enrich the individual players experience. Sitting in a bar for hours on end and idling on a street corner or lobby or something get draining and irritating after a while.
