The Grid: a digital frontier. I tried to picture pulses of data as they moved through the Matrix; what did they look like? Ships, motorcycles? Were the devices like freeways?
I kept dreaming of a world I thought I'd never see.
And then, one day...
I got in!
In game terms, Seattle's LTG is the main overarching hub that connects all of Seattle, and the Seattle 'plex, to everything elsewhere; with a Rating 9 Signal (whatever else we might decide its stats are, I think we can all agree on that,) it has a transmission range of 400 Km, putting it in constant real-time connection with orbiting satellites, every 'plex grid within 400 Km, and any device which is within its own Signal rating of reaching the LTG. For instance, my group is basically never going to not have Matrix access, since one of them has a Singularity Battle Buddy in her head with a Rating 7 Signal device, giving her a range of 40 Km. Even in the farthest reach of Tarislar, and assuming that the Tarislar transmitters are down, she'd be within MSR of Ft. Lewis and southern Auburn and Tacoma, which will definitely be enough to link her into the LTG. In most of Seattle, she'll be within MSR of the LTG itself.
This also means that you should basically never be able to get lost in the wilderness, as long as you have a commlink on you. Even if your transmitter's not beefy enough to get a signal back, unless you're way out of the realm of probability, you'll be within Signal range of the Seattle LTG, so it shouldn't be too hard to just head towards it and pray you find something civilized before the critters get you.
But for all of its utility as the matrix backbone that connects Seattle to things in the sky, and to other 'plexes within its 400 Km range, what does it look like? This became important in my game recently, because the climactic battle of the Run my group was on took place on the Grid itself.
I decided to make it a mix of Seattle's AR sculpting of an "emerald city" Wizard of Oz motief and TRON: Legacy, heavy on the TRON and light on the Wizard of Oz. Basically the Grid from TRON: Legacy with a greener color scheme. My explanation for this (IC) is that the artist they hired to design it was a huge fan of turn-of-the-century flatvids and not a fan of the Wizard of Oz, and nobody in an oversight position caught on to what he was doing, too wrapped up they were in the shiny green transparent panels.
The Grid (and you can rightly call it that, being the Local Telecommunications Grid,) is a web made out of a series of tubes; enormously huge, leviathan hollow tunnels floating high in the digital air, a web of tunnels spreading out, connecting all of Seattle and beyond. Government matrix locations appear in the midst of the grid as floating green buildings, connected by huge on-ramps, along with other major Matrix sites in the vicinity, though those may or may not have their own representation. But major matrix sites are only the half of it; by far and away the most numerous thing that goes through the LTG is going to be data, whether comm-calls or email or what-have-you.
Far below the Grid is a sea of white lights burning on the ground, forming an outline of the metroplex made out of burning dots indicating devices in connection with the LTG and official sub-grids, such as repeaters in the different districts. To get to them, data (or someone riding the Matrix) flips to the outside of one of the tunnels and drops off of it, sailing down towards whatever they're heading to. To get into orbit, or to another metroplex grid, take one of the mega-tubes out of the city.
Basically, "information superhighway" as a literal metaphor, interpreted through TRON: Legacy. Anything happening on the grid should be cast in light of constant, blazing motion, balls-out speed. I didn't shy away from giving my player's icons light-cycles when they jacked in, either, which turned what might have been an otherwise boring roll-off between Trace IC trying to track them down and them trying to analyze a virus (so they could get a full copy of it, so as to reverse-engineer a countermeasure,) into a very literal chase, complete with one player's light-cycle crashing, smashing and de-rezzing when she used a rating-3 stunt to float away from it and hover.
I'll post the stats for it (and its security measures) when I've done them. I'm sure my idea of the stats and security protocols will differ from yours. But what do you think the Grid looks like?
