I expanded my Known World Gazetteer collection. It’s all POD, but the quality is quite good and it’s way more affordable than buying the originals on eBay.
I really enjoy the Known World setting of Mystara and everything it adds to BECMI D&D. 🗺️ ⚔️ #DnD #Mystara #BECMI #OSR #ttrpg

I just saw that my YouTube channel cracked 20k subscribers! That’s kinda cool. It’s been slow going the last few years with real life obligations and transitioning the content from strategy gaming to tabletop gaming, but it’s fun nonetheless. Thanks for subscribing! 📺 #ttrpg #DnD #OSR

With half the group out yesterday, instead of our usual Castles & Crusades session, the rest of us played classic RuneQuest run by my good friend who has been running his RQ campaign for nearly 40 years. It was a blast. But a pair of Broo almost 💀 us all. ⚔️ #ttrpg #RuneQuest

One RPG goal for 2026 is to run a solo campaign. After some back & forth (+ some help from my son) I’m going to explore a D&D edition and setting I’ve borrowed from in the past, but never really dove into. My solo campaign attempt will be using the D&D Rules Cyclopedia (100% RAW) in the Known World.

One of my goals for 2026 is to get a regular HârnMaster campaign going. Bereft of local players, I’ll probably need to recruit players online…a daunting task. #ttrpg #HarnMaster

OD&D gets so many things right, including the historical accuracy of medieval garrison sizes. They were usually quite small (20-200) and in OD&D the random castle garrison roll gives you 30-180 (3d6x10) soldiers (+ added commanders & higher level fighters). That’s pretty dang close. ⚔️

I’m excited to say that I’m starting an old-school project born out of my home OD&D campaign. I’ll be posting design updates on my Substack. Link to my Substack is in my profile. I’m looking forward to sharing “Heirs of Argax - Fantasy Adventure Campaign” with people. #DnD #OSR #ttrpg

I’ve been in a creative funk lately, so I’m gonna try a few things to shake it off. One thing I’ve been looking at is running some solo RPG sessions. Plenty of people seem to like it. Some of the systems I’m wanting to try are Rolemaster, RuneQuest, HarnMaster, and Classic Traveller.

As I’ve been diving back into Rolemaster 2e over the last few days, I’ve been quickly reminded how brilliant this RPG is. PC development is the most complex part. At the table, it’s pretty smooth and straightforward. Basic math skills and occasionally using amazing charts are needed. #Rolemaster

Cracking open one of my Rolemaster 2e books yesterday has rekindled the passion. So naturally I had to bust out my box set and all the extra books I have, rereading and dreaming of running a campaign of RM2. ⚔️ #Rolemaster #ttrpg

The wilds to the north of Hawkmoor are mapped! Aside from one coastal barbarian trading town, nothing will be labeled in this region since no imperial expeditions ever ventured here. I’ve now got the western half of the greater Hawkmoor region drawn. Next will be the eastern half. #DnD #OSR #ttrpg

It’s a gloomy day here, so I decided to do some more map drawing of my Hawkmoor setting for OD&D (or really any OSR game). This👇🏻 is the region south of the city of Hawkmoor. It’s a region dominated by some vast forests and moorlands with storms hitting the coast. 🗺️⚔️ #DnD #OSR #ttrpg
