Sorry for jumping in late - I've had trouble getting registered.
The setting I want to create is intended to combine some elements of V for Vendetta, the recent Bionic Woman series, and and the old Paranoia game's feel to generate a really different look at cyberpunk.
Rather than focus on the big and obvious tech, my world will be more "under the skin". In the 21st century all the major governments went bankrupt trying to stave off the myriad disasters associated with climate change. No one could provide the health care and food needed to keep their populations alive and thriving. Seeing a chance to intervene, some of the larger corporations positioned themselves to introduce new tech - the governments would all agree to bypass the normal rules and requirements for testing, etc. if only the corporations could save us all. And they did. But now, they own us.
They've saved us basically through injecting custom swarms of nanobots into our bodies. These can be programmed to repair damage, fight disease, fight ageing, etc. But they have a downside. First, since they are passed to children through the umbilical cord, they are inherited. This means that they are INCREDIBLY EXPENSIVE. And since no one can afford these costs, the corporations - who got around all the regulations on new tech and monopolies and so forth - have added a bonus feature to the swarms that takes advantage of all the ubiquitous computing and Wi-Fi in the world. Every once in a while, the corporate computers can gain some measure of control over the hosts. This control can be benign - like getting you to slip lots of ads for products into every-day conversation (think Truman Show here). Or more overt - like coordinating a group of people to knock over another corporation's operations.
To make the game really exciting, I plan to use Fudge and have each player control TWO entities in the game. One is a standard PC - with nanotech enhancements and committments. To really make the game different, though, the other entity each player controls is one of the corporations, which will be generated using Aspects from FATE that will allow them to spend an asset to try and control another PC through the Fate mechanism (giving them suggested courses of action, etc.)
Driving the action will be the recent appearance of Keeton. This mysterious figure is all over the web and is interfering in every corporations' business. No one knows (except the GM - who ain't telling) whether Keeton is an individual with serious tech mojo, a group working to resist the control of the corporations, a corporation using a disguise, a former country trying to regain control, or even an AI-evolved from the nanobots. What we do know is that the more tech you have the easier it is for Keeton and the corporations to control you.
Big brother - and his dark, mysterious cousin - are watching.
