Does anyone produce an in-game newspaper that highlights the secondary and tertiary effects of their players actions? If anyone is familiar, I'm hoping for something like the Baldur's Mouth Gazette in Baldur's Gate 3

I love the idea of having a new edition every now and then, letting them know how their actions effect the world and how the world is changing around them. Does anyone do this, or have experience making something like this for their games?

I have done it in many of my campaigns.

Example 2

It’s cool idea, but it really seems like a lot of effort. You’d mock up a whole paper (or maybe just a front page) when all you want is for the characters to see one article.
It’s just as easy, I’d think, to have the PCs see the changes happening. Or if they’ve traveled, to hear other travelers talking in the inn about the crazy crap that just happened over there, and the PCs know it was them. That also allows for an rp opportunity if the characters want to take the credit for it — and face consequences when people know it was them.

Also, a newspaper means a printing press, which opens a whole can of worms in terms of technology level.

Thanks! I'm trying to get permission to view 😊

I actually do have a newspaper. My game is like a sandbox, where the overarching goal is to kill the BBEG, since he's just running around doing evil crud. I like to use newspapers to have them detail stuff that's happening around, and how their actions worked in-game. For example, newspapers may alert them to possible threats, bounties, and if a major event happened.

How did you build it? Do you have an editable template that you swap out headlines and photos for? Did you get an already made photo and edit that?

I usually take notes of the main things the newspaper covers and I tell my players what it says.

Yes! Thank you! That's exactly the inspiration I'm looking for.

PowerPoint, interesting! I hadn't thought of that

A newspaper implies movable type, which is an element of world building that doesn't always serve... I did it as rumors the characters have overheard...

I love how worlds full of magic that can do anything is given, but the printed word is unheard of 😅

You're assuming the magic isn't being levied against the printed word...
