As cellular networking improves, the ability to tell certain types of story become harder and harder, approaching impossibility.
Horror movies made in the last decade almost always need to justify that their protagonists have no signal, and that’s going to become an increasingly unlikely scenario. How often have you had no signal lately, compared with even five years ago? For modern games, you already have to explain a signal dead zone because it’s very unusual. For games set in the near future, the networks are only going to get more and more extensive (and, if mesh networks ever come into vogue, everyone’s a chain to the nearest node).
Occult and other weird mystery stories have a similar problem: everyone has a camera to put secrets on the internet, and everyone has a smart phone to pull them back off again. It’s particularly problematic if you want to build your story on real-world inspirations; your players only need a few points of reference to find all of the online resources you used to build the mystery, and telling them the Wikipedia page they’re looking at doesn’t exist in the game world stretches credulity.
Assuming you want to continue running modern games and/or futuristic games not set after an information apocalypse, how to you handle this prevalence?
A wizard did it
The go-to explanation that I see the most often is interference in technology caused by the mystical. Weird shit causes signal dead zones and extra dimensional beings can’t be recorded or even described electronically. This is hard to do well for a few reasons.
First, it means that you have to integrate this trait throughout your world building. It’s generally considered cheating if your magical beings can use technology perfectly well when they want to, but then deny it to the player characters whenever necessary. And not every game about the occult wants the monsters to be like Dresden Files wizards, forever blowing up any high tech they try to use.
Second, unless you are an IT professional, you’re probably not going to close all the loopholes your players come up with. Maybe it’s just because I’ve regularly had at least one programmer or network engineer at my table for the last several years, but I’ve grown accustomed to never satisfying them with a simple block. Saying that something technological doesn’t work correctly simply opens you up to a series of increasingly complex steps to route around the problem that they would use should they encounter something like it at work, many of which you won’t even have realized were possible or have any way to adjudicate.
Third, the natural response to the previous is a blanket, “it just doesn’t work, okay?” This tends to piss the programmers right off (unless it can be pointed out that their characters have less computer knowledge than they do, so they should have put more points into it). But even in the simplest denial, you tend to shake faith in the world. Players are becoming more and more complacent with information solutions to real world problems, and denying them in game sometimes stymies rather than inspires creativity. Technology not working the way we expect it to is already an out-of-context problem for tech junkies, and it’s only going to get worse as time goes on. If Googling doesn’t work, what do you do next? If it prevents an online search, is an electronic search for a dead tree book at the library going to work better?
Finally, frequently jamming technology might be more of a survival risk. A group of secretive beings that regularly causes cellular outages is eventually going to have their secrecy blown wide open by something as innocuous as a crew of telecom employees trying to figure out why their customers keep complaining about roving dead zones. That’s awesome if your protagonists are those telecom employees, but maybe not so much for other campaigns. And your IT-savvy players will try to use any “rules” you put in place to their advantage in detecting threats.
Quis custodiet ipsos custodes?
Perhaps a more plausible solution, given all the governmental wiretapping revelations, is that networking always works, but you might not want it to. While shadowy conspiracies with a back door into various telecoms can’t necessarily destroy information on the internet, they can potentially be alerted to people looking for it.
This mode relies on the protagonists being more worried about the men in black showing up than they are about the monster, but that kind of paranoia tends to be pretty easy to create. Also, from a mystical standpoint, “I have a spell/power that alerts me that someone’s looking for me, even via an internet search,” is probably an easier sell than, “magic cleans my traces from the internet entirely.”
Essentially, this says to players that they can use technology to investigate, but if they don’t cover their tracks they’ll give away the element of surprise and possibly have even more threats dropped on their heads. The PCs need their hacker not just to do a search, but to correctly configure TOR and come at a topic via search terms and linking that won’t set off any alarms.
And in a future game with mesh networks, you can even pull off the trick that suddenly there’s signal… because the enemy is in between them and the cell tower, and they’re sending all their searches and conversation right through its own computer.
You can’t ever split the party
Players in most games don’t ever want their characters to split up, so much that “never split the party” is a meme. GMs love to throw out threats against lone PCs, and the players have learned this lesson too well. Refusal to split up, even when it makes sense, is almost pathological.
This is an area where taking communication for granted is a strength. I’ve found that players are much more likely to split up in modern games where they can instantly call or text to share information or ask for help, and even more likely in futuristic games where they don’t even have to grab a phone to accomplish this, but can simply stream their permanent video feed to friends in real time.
You don’t even have to cut the feed to make this work. Normally, when you’re describing something terrible happening to a split PC, the other players at the table are having to struggle to avoid metagaming with information they know but their characters don’t. Getting it all on speaker phone while unable to do anything more than shout advice can make them more invested, and lower the metagaming dissonance.
Even if you’re not regularly going to pile tragedy on a lone party member, open communication can be a boon. Unless players have extensively played games where party splitting is common, it can be hard to retain focus and be polite when another player is getting spotlight time and you can’t interject in character. That is, they’ll tune out and become a distraction to the GM and active player. Giving them the ability to keep up with what’s going on in-character and to potentially give advice but not physically affect what’s going on is likely to keep them much more invested without detracting too much from the main player’s spotlight time.
