What hasn't been mentioned at all yet is Twitch and Streaming and how it may impact 6E.
3 years ago you were lucky if there was 2 games on the D&D page and only Rollplay had more then 5 viewers, but today there is consistently a dozen games in the page, and even that is really impressive because of its consistency. Aside from the, about a dozen, staple games on Twitch (Hearthstone, Overwatch, League of Legend, ect.) literally every other multi-million dollar triple A game dies off after a few months. The new Legend of Zelda game, which is the highest rated game of all time, first contender of game of the year, and came out about 5 months ago, it has the same amount of channels playing it as the D&D page, and less viewers.
3 years ago there was really only one channel playing TTRPGs on Twitch with any degree of success and that was Rollplay, now I can easily name half a dozen. Plus Companies are allowing some of these channels to use their IP, and I'm talking about Geek & Sundry having permission by the owners of Star Trek, to play a Star Trek RPG game on their channel, and HyperRPG got the rights to play a Power Rangers RPG by Saban. And of course D&D has started their own channel, which is growing. Plus all the cross pollination between all of these channels is insane, they are not competing at all, they are all interested in one thing only, growth. And they are receiving it. It's only getting bigger, more channels are popping up and being supported by the streaming community, more companies are showing an interest, more celebrities are participating. D&D is entertainment, it is a spectator sport.
Its not going to be too long untill a TTRPG is made specifically for streaming.
And with D&D proper in the business of streaming, I'm sure they are learning how the medium works and gathering information and data, and learning from successful channels and from their own failures. They're only going to get better at it.
So then I wonder how much of all this will be reflected on 6E. the DMG is a book made specifically for a DM to run a game, and the medium used to be exclusively the tabletop, but more and more its also streaming.
Do you think it will have tips on how to run a stream of D&D? Maybe talk about cross chatter, when to have breaks and how long they should be, ect...
Some channels like HyperRPG are very viewer interactive. Maybe the 6E will have a guide on how much the viewers need to donate to give a player or the DM advantage on a roll, maybe talk about what parts of the system are okay to let viewers fiddle with and which not to. The same way it gives advice to DMs on tweaking their game
What about rules and options specifically for streaming? Like a rest mechanic that is optimal for streaming. because they found out that the audience likes it when there is a "breather" or inter-party interaction every 45min, so they tweak the resting mechanism to need to happen about every 45min.
Or maybe borrow small mechanics from a different RPG that was made specifically for streaming?
Oh, what about deliberately excluding certain things that previous editions had specifically because they assume that 6E will be watched by a broader audience? Like maybe they get data that says the audience doesn't like Advantage/Disadvantage, so they get rid of it for 6E.
I don't know what, if any, impact streaming will have on 6E, or even what that would look like. But I've read on these boards about how 4E was affected by videogames and MMOs. And D&D isn't afraid of being influenced by culture trends. But at the same time, still no PDFs, so its hard to say for sure what sticks and what doesn't.
