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.

It’s been D&D “comfort food” reading the last two evenings with my favorite editions of the great game. Yesterday was 🍺 + AD&D 2e (my favorite edition). This evening it’s 🍺 + B/X D&D (my second favorite edition).

All set up for our first game of War of the Ring this weekend. ⚔️ #WaroftheRing #boardgames #wargame #LotR

Even though I’ve been running Castles & Crusades for a number of years now and it’s my “D&D” of choice, I constantly reread parts of the PHB and CKG. It helps to further internalize rules and procedures. It’s also the rare game where I read every spell. ⚔️ #CastlesandCrusades #DnD #ttrpg

Got some more classic Hârn goodness in the mail today. Aside from the old price sticker on the cover, it’s in mint condition. Hârn is, without a doubt, the best medieval (and medieval inspired) fantasy setting ever developed for TTRPGs. ⚔️ 🏰 #ttrpg #Harn #DnD

Today marks the 36th anniversary of the fall of the Berlin Wall. The ultimate symbol of socialist oppression & evil was torn down by my fellow Germans who had had enough of the murderous socialist regime. Never forget the evils of socialism and our natural drive for liberty. #BerlinWall #Mauerfall

I’ve been spending a lot of time in d100 RPG land again recently: reading, studying, and prepping. I’ve been especially focused on RuneQuest, Jackals, and HarnMaster. I absolutely love these games and systems. I’m also starting to (finally) read Zweihänder. #ttrpg #RuneQuest #Harn #Jackals

Our Pendragon Classic Kickstarter has five days to go! Having passed the first two Stretch Goals, Double the Dice and GM Screen, we're pleased to announce new Stretch Goals to carry us through to the end of the campaign... #pendragon #ttrpg #kickstarter

If you’re serious about good fantasy worldbuilding, there are two settings I feel are must-reads to understand how to do it properly. They both present vastly different yet brilliantly detailed worlds: Glorantha and Hârn. Buy some PDFs and study them. #Glorantha #Harn #ttrpg #DnD #RuneQuest

Morning reading in preparation of future adventures in Glorantha using classic RuneQuest. ⚔️ 🏺🏛️ #RuneQuest #Glorantha #ttrpg

After 2 years of designing and playtesting, book 1 (the “PHB”) of my OSR game “Falenburg” is done. Next up is finalizing book 2 (the “DMG”) which includes compiling a few years of playtest notes, thoughts, random tables, etc. A lot of book 2 is already done. #OSR #DnD #ttrpg

My hand drawn map of the city of Hawkmoor and its surrounding lands for our OD&D campaign. It’s a bit (very) rough in spots, but it’ll do for the table. I’ll need to scan it, do some touch ups and label it. #DnD #ODnD #OSR #ttrpg #fantasymap

I’m bummed I missed out on GameHoleCon due to illness. Next Cons won’t be until spring, when I’m planning on attending GaryCon and DaveCon. Until then we’ll be gaming through the fall and the long, cold Wisconsin winter.
