I always had the soft spot for the cyberpunk milieu and I suspect many in GDW also did. Afterall, if they could not make a credible dark future, as there were too many fans whinning and saying that cyberpunk was not science fiction.
That's funny you say that. My view from the outside was that I always thought GDW didn't like cyberpunk. I think they saw it as a passing fad, but catered to it with 2300 in an effort to jump on the cyberpunk bandwagon that was
really huge at the time in an effort to boost sales. The integration between 2300 and the cyberpunk genre was interesting, but I don't think it was wholly successful. Then they tried making their X-Files type RPG, Dark Conspiracy, but ruined that (imo) with everyone driving around weird retro 1950s cars with lots of hoses and the women dressing like marching band majorettes.
I always thought that 2300 attempt to become "vanilla" cyberpunk was pretty tragic, because 2300's background had huge possibilities to set it apart from other Cyberpunk settings. I once had an idea that basically followed the concept that off-world colonies was nationalism's last gasp.
I would move stutterwarp detection a bit back (or move the game start to 2200 or something and get rid of the Twilight War) - leaving more time for humanity to (overexploit) the solar system. Trapped in a single solar system, bound together by economics, it would follow the Cyberpunk credo of a "rotten civilization unable to fall." Corporations and other profit-pursuing entities would dominate humanity by this time, while nations to try and increase their collective bargaining power against the multinationals would have increasingly banded together into federations and unions, but whose power was clearly waining.
You enter into this stutterwarp. Suddenly, humanity is free the solar system, at least in theory. By this time the multinationals are secure in their de facto control of humanity - there's the "cyberpunks" who basically are a social pressure release valve - a place for the young and the firebrands to go but the corporations have learned by now that such groups don't play well together so will never be more than a small nuisance, but it keeps the masses happier, and the Darwinian social mechanism produces brilliant corporate scientists and leaders at times. The corporations frankly don't know what to make of stutterwarp. They don't like exploration because it's hugely expensive in the short term and the effects of off-world colonization is a factor that's going to rock their carefully arranged coalitions and partnerships to exploit humanity for the profit of a few.
While traditional cyberpunks are parasites - unable to survive away from leeching resources from the multinationals to develop their "black market" tech or raiding corporation databases for information and so on - stutterwarp appeals to a larger group of the disenfranchised. Skilled corporate workers in "first world" countries who find themselves outsourced of a job, middle-management who realize they'll never get ahead because anagathics and AIs don't age or retire, nationalists who don't like how their nation has sold their souls to the doling out of paychecks by the corporate overlords. These people pool together their resources and strike out from the Sol system to start again. Ironically, this means that most colonization is done by people from the (former) "western" world who have been marginalized by brilliant workers from the (former) third world who are willing to work for less.
The multinationals who control Earth by this time are content to worry and plan on Earth, finding that exploration is much easier to do when people like that are willing to do it for you. Some of the smaller companies, more agile in their thinking, are funding their own colonies. The more successful groups that rise up from such colonization they attempt to buy-out and co-opt into their corporations and the more hospitable colony worlds are increasingly corporate controlled. But there's still a wide universe out there of idealists, nationalists, religious separatists, and so on who just don't want to play ball. They're arming, making new nations out there, some of which want to eventually liberate their home countries from "corporate occupation."
Contacts with aliens is equally different in such a universe.
The Ebers are a sideshow. There is a low-level war between the thinly stretched power of the multinationals on one side and the Ebers and human partisans on the other trying to prevent the Ebers from being exploited.
There is no "Slaver War" - the leading power of the Sung allies itself with a corporate power bloc, while other corporate blocs ally themselves with lesser Sung powers. Without the moderating effects of "common humanity" on Earth, the corporations have driven the Sung to a brutal civil war on their planet, killing millions if not billions of Sung. However, the Sung don't bear a grudge towards humanity since humanity is doing its part in helping the Sung technologically (technical advisors, weapons designs, and so on are all being shared by corporate supporters) - the Xiang remain slaves of the Sung.
The Pentapods have social problems of their own. Humanity (badly) mirrors their own existence. Individualistic "Bullets" being set out to the frontier to explore and develop to reap the rewards for the "gods" (corporations) back home. The Pentapods aren't blind, however, and their "bullets" are seeing how humanity's "bullets" don't get along with their "gods" and this has caused rifts in the Pentapod race as Pentapods are wondering exactly why they're doing this for their gods. For the now, their "gods" have withdrawn from their exploration "bullets" to prevent further meme-contamination, leaving the exploration "bullets" time to develop on their own. This has little hope of ending happily, however, and its said that the gods are developing new genetic and chemical methods of enforcing servitude.
The Kafers are the wildcard. Finally, there is the force that can bring down the "rotten" society of mankind. The barbarian tribes at the gate and they're sweeping all resistance before them so far - the powerful battlefleets of traditional 2300 don't exist - navies are expensive and unprofitable and customs cutters and bulk freighters are a poor match against Kafer Alpha and Delta battleships. So far, humanity's response has been haphazard. Sometimes resistance is vicious, othertimes laughably disorganized. Indeed, the Kafers haven't conquered humanity yet because they're encountering the Ylii problem - it's often more fun to fight each other than humans. The corporations have repeatedly sent emissaries to the Kafers in the hopes of creating a "profiting sharing" arrangement to utilize Kafer muscle to keep humans in line while offering Kafers "smart drugs." Fortunately (or unfortunately) Kafer intransigence has led such efforts to fail. Entire worlds along the "French" arm are dead or conquered by the Kafers. Kimanjano and BCV fell when corporate militaries pulled out when accounting AIs computed the lack of profitability and waste of corporate resources could not be recouped and the Kafers are learning that targetting corporate industrial facilities from orbit is the best way of making the more effective human forces withdraw. Back on Earth, the corporates AI cores and anagathic executive boards shudder, washing away the unpleasant thoughts with software revisions, ever more complex artifical realities, tailored recreational drugs, and parties. They enforce a strict "business as usual" regime on Earth while they "explore solutions" to the "Kafer Issue" - one that doesn't involve too much loss of profit and loss of market share to other companies. Meanwhile, middle-upper management has to deal with the fallout, and there's hope for humanity in that as these managers are now putting their heads together within corporations and even across corporations. They realize the fossilized leadership is only going to react when the aliens get to Alpha Centauri, but by then it'll be too late. Far too late. Unfortunately, such managers are stuck in their positions precisely because they lack qualities such as initiative and leadership to rise higher (or jump ship for the frontier). So far, this is only grumbling over luncheons and in the gyms as that "someone" should do "something." With the tacit support of such corporation-controlling elements, however, leadership (perhaps even from the outside) could enact a violent change in control of the corporations giving humanity a chance to resist the Kafers before it's too late, but will that happen?
