I’ve got the finalized “early access” of the Falenburg Tome of Adventure done! I’ve printed out finalized play test packets + maps. I’m busy working on the Tome of Judgement now. Loot is done and the bestiary is nearing completion. I’m pretty excited to get it to this stage. #ttrpg #osr #dnd

We don’t need new TTRPGs! That seems to be a very common sentiment out there. But…what if you really want to create a new game…even if it will probably get lost in the void of game glut? #ttrpg #dnd #osr

I had some fun using Hexkit to create a realm for Mythic Bastionland with the random generation system from the book. This is the player-facing map. The GM version is full of info. 🗺️ ⚔️ #ttrpg #fantasymap

I’ve been spending a lot of reading time the last couple of weeks with these👇🏻 “D&D/OSR adjacent” games. So many fun design aspects that I’m also incorporating in my own OD&D games + running them as well. Expanding the mind so to speak. ⚔️ 📚 #DnD #OSR #ttrpg

I’m pretty excited for this👇🏻 one! Just arrived in the mail. Can’t wait to run some Mythic Bastionland by @bastionland.bsky.social. And yes… @3d6downtheline.com played a part in inspiring this purchase ⚔️ 🏰 #ttrpg #OSR #MythicBastionland

I’m outlining a new RPG project idea I have. I’ll be using Basic Roleplaying from @chaosium.bsky.social as the core game engine. I love BRP and the toolbox it gives me to fit with the themes and mechanics I have in mind. ⚔️ #ttrpg

I’m so stoked! My copy of Castle Xyntillan arrived today and I can’t wait to integrate it into my ongoing old-school D&D campaigns. I’m mainly using OD&D/Swords & Wizardry, but I’m also gonna use this with Castles & Crusades. ⚔️ 🏰 💀 #DnD #OSR #ttrpg

I’ve got a new video out where I discuss why I consider Hârn to be the best medieval fantasy setting ever designed (emphasis on medieval). I also offer evidence that counters the age old myth that Hârn is very “low fantasy” ⚔️ 🏰 #Harn #ttrpg 📺 link👇🏻 youtu.be/zU_auCSOayI?...

Time for some HârnMaster prep. ⚔️ #ttrpg #Harn #HarnMaster

I’m busy prepping for a home RuneQuest campaign. Even though I’m using RuneQuest 2e as the foundation, I add content from the current RQG edition as well. So I guess I run RuneQuest 2+e. ⚔️ 🏺🏛️ #RuneQuest #ttrpg

I have recently expanded my Shadow World collection focused on the continent of Jaiman. An amazing setting I’m only now discovering for Rolemaster 2e. #ttrpg #Rolemaster

Mail call from! Shadow World is the setting designed for Rolemaster in the ‘80s & ‘90s. I never used it “back then” and thus decided to explore the world now. Can’t wait to discover it! ⚔️ 🗺️ #Rolemaster #ttrpg

It’s a Rolemaster 2e kinda morning. ☀️ ☕️ I’m mulling over some ideas for a “small group” (1-2 players) or solo campaign using RM2. ⚔️ #Rolemaster #ttrpg

After spending Sunday playing Chainmail with my son, I’ve had wargame campaigns on my mind (also in the context of OD&D or AD&D campaigns). So I’m once again reading this great book on Tony Bath’s wargame campaigns, including his famous Hyborian campaign. ⚔️ #wargaming #DnD #ODnD #ADnD #ttrpg #OSR

Time for some Chainmail using 15mm figures. They’re not painted yet, as I’m still deciding which Greyhawk armies to represent on the tabletop. ⚔️ #wargaming #ODnD #DnD #ttrpg #OSR #Greyhawk

I’m currently working on the regional random encounter tables for my “Heirs of Argax Fantasy Adventure Campaign” setting project for Swords & Wizardry. My inspiration are the 1983 Greyhawk tables. The regional and geographical feature focus of these tables is great. ⚔️ 🗺️ 🎲 #DnD #OSR #ttrpg #Greyhawk

After a crazy busy last 2 months of work, I’m very excited to be heading to GaryCon next week! Who of you will be attending? #GaryCon

Ok…when you see these👇🏻 classic D&D books and the editions they (in particular) represent, what style of fantasy themes, adventures, and settings do they evoke/imply for you? ⚔️ 📚 #DnD #ttrpg #OSR

I got back from a 2-week Europe trip yesterday night and a box from Troll Lord Games was waiting for me with the BackerKit campaign rewards for the Adventurers Backpack for Castles & Crusades. So much awesome C&C stuff! 📚 ⚔️ #CastlesandCrusades #DnD #ttrpg #OSR

My 13-year-old daughter wants me to run D&D for her and some friends. I’m gonna go with B/X (OSE). We’ve had a lot of fun over the years running OSE with the kids’ friends who were new to D&D (and TTRPGs in general). ⚔️ #DnD #OSE #OSR #ttrpg

This is a painting my parents own, depicting a 17th century Dutch scene. It’s an inspiration for a settlement in my Falenburg RPG. #OSR #DnD

New video! In this one I highlight and discuss the books and stories that I consider essential (possibly required) reading for anyone running (or even playing) old-school D&D and OSR games. 📚 youtu.be/Jd9bda5DED8?...

This evening is spent going through the AD&D 1e Wilderness Survival Guide to pick some of the optional rules I’ll be using. I’m a fan of wilderness travel in D&D and there are some great tools in here for survival rules. Plus it’s got amazing art throughout it. 🌳 ⚔️ #DnD #ttrpg

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

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

I’ve got a new video out discussing my “Top 10” OSR games. ⚔️ 📚 #DnD #OSR #ttrpg 📺 Link👇🏻 youtu.be/hikiNq1BKic?...

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

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

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.

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 www.realmbuilderguy.com/2025/12/a-cl...

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

I’ve got a new blog post discussing setting a base layer of limits and parameters for an OSR campaign. ⚔️ www.realmbuilderguy.com/2025/12/sett...

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

New blog post introducing the “Heirs of Argax Fantasy Adventure Campaign” ⚔️ #DnD #OSR #ttrpg www.realmbuilderguy.com/2025/12/intr...

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 decided to set up a Substack. Not sure if I’ll like it, but figured I’d give it a go. Follow & sub👇🏻 realmbuilderguy.substack.com

I’ve got a new blog post out where I outline why I love playing classic TTRPGs, oftentimes over the new “sleek & polished” modern games. #ttrpg #OSR #DnD #RuneQuest #Rolemaster www.realmbuilderguy.com/2025/12/play...

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’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

“Your OD&D will vary.” That’s good and in the spirit of the original game. My foundation is the original 3 books. Then I use aspects of the OD&D Supplements, Holmes Basic, Judges Guild, Strategic Review, and Dragon. I use the AD&D Monster Manual. I also add some of my own stuff to it and experiment.
