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

I completely agree

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

Required Books to Read for Old School DnD and the OSR YouTube video by Realm Builder Guy

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. 📚

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

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.
