'From Maps to Myths': today at tabletop.me, MOB was part of a panel with industry peers Chris Birch (Modiphius), Luke Gygax (Gaxx Worx) and Steven Medway (Blood on the Clocktower), discussing different approaches to creating settings for #TTRPGs. Matt Wilson hosted.

Yesterday the RPG Realms zone of tabletop.me in Dubai 🇦🇪 was packed with players, all day. And it was exciting to see so many newcomers trying #TTRPGs for the first time!
Plenty of games to choose: we're running #CallOfCthulhu demos, and there's also more CoC & #Pendragon happening too. Plus D&D etc

How do you spell 'Cthulhu' in Arabic?—in a workshop at tabletop.me in Dubai, MOB introduced aspiring #TTRPG creators Hamda, Yann, Roua, Yazen, and Eisa to Chaosium's community content at @drivethrurpg.com; maybe one day soon we'll see our first releases in Arabic in the Miskatonic Repository!

We're excited to be part of the RPG Realms zone at tabletop.me, the Middle East's first dedicated tabletop games convention. Our friends from the Gulf Roleplaying Community are running this area: here's GRC leading lights Mo and Omar with Andrew, MOB, and Barbara from Chaosium.

With projects such as these, the Chaosium Nostalgia Department always gets heart-warmingly surprised every time by how much excitement, delight, and enthusiasm each distinct Classic project brings. The 20 days of the campaign have gone by in a blink.

It was exciting to watch the final 24 hours of the #Pendragon Classic Kickstarter and see the total funding break $140,000 in the last few minutes. And reach exactly 1400 backers. As we said, we're gonna need a bigger Round Table.

Whoa, speaking of treasures at Chaosium Con EU in Gdansk, look what we found deep in the warehouse. These must be the last remaining unsold copies of Horror on the Orient Express (the boxed TTRPG supplement, not the coming board game).

A packed Community Content panel at Chaosium Con EU last night. We're blessed to have such a vibrant and collaborative creator community in our programs at @drivethrurpg.com. It was heartening to have so many aspiring creators join in, keen to bring their ideas to publication too.

Inevitably, one cannot help but speculate about what Greg himself would say on our 50th anniversary: "Gee, guys, whatever you do don’t make it all about me!", and then he would remind us that "We are all Us."

Since then, we have published over 700 more games and supplements, including RuneQuest, Call of Cthulhu, Basic Roleplaying, Pendragon, ElfQuest, and Rivers of London, to name but a few.
