I got back from a work trip this evening and look what was waiting for me! More classic RuneQuest awesomeness from @chaosium.bsky.social! The quality of their POD copies is really great. ⚔️ 🏺 #RuneQuest #ttrpg

I agree. But I’ve found online sources for those.

Playing some classic RuneQuest this evening. Very stoked! 🏺 ⚔️ #RuneQuest #ttrpg

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

Time to dive into this solo RPG thing. Exploring the far north in Heirs of Argax today. ⚔️ #DnD #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

Thanks 😊

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

Excellent!

I got a few new OSR products in the mail today. ⚔️ 📚 #OSR #DnD #ttrpg

Despite my love and nostalgia for grey box Realms, my vote always goes Greyhawk

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.

A Cleric State of Mind 2025 has been my " OD&D " year with me dedicating a lot of time into studying this edition, its various sources, and running a detailed camp...

New blog post! In this👇🏻 article I discuss my experimentations and tinkering with the OD&D Cleric class during this past year. ⚔️ 🙏🏻 #DnD #ODnD #OSR #ttrpg

That’s what I’m also considering. I really like HM3

I’m quite drawn to the “all-in-one” hardcover book presentation. I’ve seen some videos on it and it looks very intriguing.

Talking to some of the HarnMaster peeps on here (like @ardwulf.bsky.social), have you given HarnMaster Kethira a go yet? #ttrpg #Harn

It’s an evening of 🥃 and Hârn. ⚔️ #Harn #ttrpg

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

I wish more people would appreciate the brilliance of HârnMaster and the setting of Hârn. True 💎 of the TTRPG world. #TTRPGs #ttrpg #Harn #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

Some new Castles & Crusades additions arrived yesterday. They look amazing and are packed with useful content and info for any C&C campaign. #CastlesandCrusades #DnD #ttrpg

I play RQ2, which has great random encounter tables and reaction tables.

I really like his stuff. I don’t need any specific solo rules. I do like procedures for things and random tables, so those games work for those aspects.

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.
