Well, aside from the changes to the mechanics, how has the fluff changed? What year have they advanced the timeline too? Any notable changes to long standing NPcs? etc.
I played 1ed, 2ed and 3ed, but have yet to pick up the 4th. Major changes to mechanics aside, how has the world changed?
The biggest change is the wireless nature of the matrix, which is both a system and setting adjustment. The pocketsec has been replaced by a Comm. Not a huge difference to the common joe but major to a runner. Comms have the power of a full cyberdeck, plus they can provide computing power to various devices which eliminates the need for the most common cyber.
Cybereyes? Replaced by contact lenses or glasses. Imagelink is handled via radio (wifi) or an induction system across the skin (skinlink) to the Comm.
Smartlink? The gun has wifi or skinlink and talks to the contacts or glasses.
Datajack? Get a set of trodes built into a hat/helmet/headband or a small jar of disposable nanopaste and get direct neural interface.
VCR? trodes (and current gen datajacks) are now capable of interfacing with those "hind brain" nerves the old VCR used to touch. Simply get trodes/jacks, put a simsense module on your Comm, and buy a relatively cheap Command program to be a rigger. (There is still a VCR module, but it is now a cybernetic co-processor that provides bonus dice. Very essence cheap)
Cyber ears? earwigs with tech embedded. Uses wifi/skinlink to share audio feeds.
Headware radio? add a subvocal mike to your earbuds and your comm can direct-link to other devices in range. Add some encryption and you've got a secure channel.
Most every device has "Augmented Reality" (AR) interfaces. Imagine a virtual dashboard broadcast to your Comm and displayed by your contacts. You interact either with the Comm's keyboard/pointer (think a Treo or Blackberry), datajack/trodes, or with feedback gloves (Johnny Mnemonic, only more like leather driving gloves).
Everything comes by default with some AR presence, at the very least in the form of the RFID tag. Walk into a store and you may not find prices posted. Pick up an item and your Comm grabs the RFID tag data (which may include a little sales brochure) and queries the price. BTW, this means you can be tracked by your RFID tags. They don't have long range but there are tag readers
everywhere. "The Man" (let's say "Mall Security") can track you as you pass through each store's security scanner. Your tags don't say "Owned by Evil Shadowrunner" or anything but how many other people will be wearing *exactly* what you do? And I do mean exactly, they'll even know what kind of underwear you are wearing.
Appliances and vehicles have an interactive AR component. Your car projects a HUD via AR; less distracting to other people and fewer parts to wear out. AR often gives you a bonus as it provides a dynamic interface that changes based on what you are doing or at the very least, access to a real-time help menu.
Going full VR requires datajack/trodes and a relatively inexpensive simsense module. Hotsim is enabled by slipping some cred to the geek at the RadioHut. Riggers just need some specialized software (Command utility, legal & cheap) on their Comm to get the full effect of an old VCR and can be completely cyber free. Hellooooo rigger adept.
System wise it means that you can hack people's comms directly. SR matrix security has always been either tissue paper or a bunker and this extends that to the common man. Every joe schmoe has a comm, meaning every joe schmoe is a potential target for hackers. Joe's main defense is the same as other sheep-like herdbeast: sheer numbers to keep the odds low and having nothing that is particularly of value.
For a runner it is a problem. Most people use a 2-layer comm system. They keep a "legit" comm around that holds their current fake ID and that does all the stupid things that joe schmoe would do. Then they have a "working" comm that is often completely off-net to run their combat toys. On a run they keep the 2-layer system with the "working" comm connected to their toys but with a highly protected "secure" comm to allow communication. That way even if the "secure" comm network gets cracked, their guns don't eject their clips and their imagelink doesn't display goatse.
