Posts

From the people making tabletop RPGs: rough ideas, questions for other designers, design notes, postmortems, how-tos, the occasional essay, and updates from the projects being made here. Short is fine.

    I conceived RPG Lab to be the place where RPG designers post their game while they're still working on it - especially if they don't yet have a website of their own. And that already works well. But project links can be somewhat long, since…

    After an amazing time at Gamehole Con last week, I figured it was time for some small improvements to RPG Lab. Posts The Posts page now shows both standalone posts and project updates, with toggles to filter by one or the other. For…

    I'm literally writing this while I'm sitting in the plane, about to take off. Gamehole Con is my favorite con, and this will be my fourth time attending. If I have a chance, I might even run an impromptu playtest of Tagline. Looking forward…

    I recorded a short video about RPG Lab. The first part covers why I built the site. The rest is a walkthrough of the homepage, projects, playtest calls, posts, and the project editor. If you've been meaning to tell a friend or a fellow…

    I just launched the first set of user badges. These show up in most places you'd expect them: the homepage feed, posts index, post comments, playtest roster, message threads, and notifications. For now, the following badges exist: Designer…

    Another fix / improvement: When someone posts a comment on a post or responds to a playtesting thread, the recipient already got an email notification (if they opted into this in their settings). But previously, the only way to reply was to…

    Since last week's launch, I've rolled out a bunch of improvements based on feedback and observations. I'll list those in a separate post shortly, but here I want to highlight playtesting improvements in particular. The reason to single…

    I am interested in getting feedback about what type of content game masters and players might like to see in a campaign setting. The campaign setting for Gods of Aumin is the world of Krystarum. I am planning on an epic world map, sample…

    It's been exciting to see the first projects appear on the site. Keep 'em coming! But I also have a feeling that some of you may be hesitant about adding your projects or making them public, so everyone can see them. So I wanted to share…

    I just removed the invite gate and waitlist, so everyone is free to join now! It's been great to see the early momentum this week. The site is slowly starting to fill in with real projects, updates, posts, comments, and even a playtest…

    Last updated: October 4, 2026. This is a living document. If something is missing, wrong, or dead, leave a comment and I'll fix it. Tabletop RPG design has many different aspects: mechanics, writing, layout, art, playtesting, licensing…

    Nice work, Mirko, the place looks great! I wish I had more time to design games, adventures and other RPG materials, but I'll definitely do it here when that time magically materializes...
