Exiles & Partisans PNP & New Projects
about 1 year ago – Mon, Apr 01, 2019 at 12:45:42 AM

Hello from PAX East! 

First, I want to say a little thank you to the many fans who have come out to Boston and stopped by the booth. It's been a pleasure meeting you folks and getting a chance to show you the Underworld Expansion in person.

Today we're releasing the final print-and-play kit of the campaign: the Exiles & Partisans deck. The original deck in Root was built mostly as a compliment for the core game design and was, in general, conservative in nature. While many cards could be leveraged in interesting ways, most of them were only good in certain circumstances. In contrast, the Exiles & Partisans deck is built around a completely different ethos. The special powers in these cards are strong and often game-warping. Like the expansion factions themselves, I wanted the deck to push the limits of designs and to offer new strategies to old and new factions alike. 

After things calm down in a week or so, I'll be writing a longer design diary about the creation of the deck and how it works. If you'd like to take a look at it, you can find the new deck here.

One of the best parts of going to a convention is that everyone on the team has a lot of time to brainstorm and work on new projects. Even though shows like PAX are a lot of work, they also function a little like creative retreats for our staff. Over the past few days we've spent a lot of time talking about the future of Root and the kinds of places we want to take the design. There are a lot of exciting things happening behind the scenes right now that we'll say more about later, but, in the short term, it's looking like we may be exploring a fan-driven smaller expansions in the near future, perhaps even a design contest. Details to come! 

Finally, we wanted to let everyone know that our partners for the Root role-playing game, Magpie Games, have a Kickstarter ending today for Wizard Kittens. Normally we don't do any cross-promotion, but, because we were already working together on the role-playing game, it only seemed natural to have Root's most prominent cat featured on a card. You can find their Kickstarter campaign here.

There are many questions popping up in the comments and Kickstarter messages and it is very difficult for us to track. If you have any questions or concerns please contact us at Remember that since most of us are in Boston there will be some delay in getting back to everyone.

Hey everyone! We are almost down to the last 72 hours of the campaign!

As a  thank you for your support we are adding a new extra to the campaign. We are adding 2 more Vagabonds to the mix that Kyle, Cole, Nick and I have been working on at PAX: East.

The Harrier is a squirrel character that will have a movement based action.

The Adventurer is an Owl character that will have a an advantage while questing.

The Vagabond cards will be in the Exiles and Partisans deck and we will include new meeples for them in the meeple packs. 

There are many questions popping up in the comments and Kickstarter messages and it is very difficult for us to track. If you have any questions or concerns please contact us at  Remember that since most of us are in Boston there will be some delay in getting back to everyone.

Thanks again and we will talk to you all soon!

Digital Rules for Root
about 1 year ago – Sat, Mar 30, 2019 at 01:41:13 AM

Hi everyone,

Over the past couple of days we've been out here in Boston preparing our booth at Pax East and showing Root to convention attendees. The show has been great so far, and we're all excited for what the next few days have in store.

That said, this morning I wanted to share with you a small bit of news. Over the course of the campaign, many people have asked us if the success of the campaign would unlock some kind of secret stretch goal. As I've said in the comments section, the answer to that question is no. At the same time, this campaign has reminded us of the outstanding community of players that have gathered around Root. It's success is an incredible testimony to you all and we want to find ways to say thank you. So, as the campaign comes to a close, we will have a few small surprises for everyone. 

Today I want to share the first of those surprises: a digital adaptation of the Law of Root. We hope that this digital version will be extremely useful for quickly looking up faction specific rules on your computers, tablets, and phones. You can use the digital rules right now, and we’ll be updating with the new factions and map-specific rules once they’re finalized. We’ve been working with Jason Kotzur on this project, as he’s developing a system to make digital rules accessible to players without a lot of intensive development and maintenance from publishers. This is still an early version, and Jason is working on a few known bugs. We invite you to explore the adaptation (link: and reach out to Jason if you encounter any bugs or have any feature suggestions. Here’s quick word from him below.


I’m on a small crusade, like a noble Vagabond, to make tabletop rules more accessible to players, through digital rules adaptations that are easy to search and navigate. If you click on the link provided, you will discover that you can now easily access the Law of Root (Third Printing edition) on any device connected to the internet, including the one that you’re using right now. There’s a bit more happening behind the scenes, but the really exciting thing is that this process uses the original rulebook files as a source, which means it’ll be super easy for Leder Games to update with the all new content. 

I’ve written about the process in detail on my website (link:  which you might be interested in if you’re in the industry or strongly believe in the emancipation of content from medium, as I do. Please feel free to send me an email (jwkotzur at gmail dot com) if you’ve got any feature suggestions or would like to pursue an adaptation for a game that you’re working on.

I’ve identified a bug on Chrome iOS (and possibly other devices) which pops up when using the Find feature, and not properly closing it. Details on site. Please let me know if you experience the bug on any other device, and if you pick up anything else that doesn’t seem like it’s behaving as expected.

Cheers, Jason

We know that Root can be a little overwhelming for new players, and we hope that these digital rules help make the game a little more accessible. When Jason first showed me the project, I was floored by how well-executed his digital rule-book was and we are delighted to be working with him on this project. 

Alright, that's all for now. Take care everyone!

Off to PAX East!
about 1 year ago – Wed, Mar 27, 2019 at 11:21:37 PM

Hi everyone,

This morning everyone at Leder Games is flying out to Boston for PAX East. This is a special show for us. At this time last year we had just submitted Root to the factory and spent the convention celebrating the completion of the project and playing a lot of Root. Now, a year later, we have lots of new Root content to share with everyone. 

Come by the booth if you'd like to demo the new maps or factions. Almost everyone on our staff will be at the show, so if you'd like to meet us please come by and say hello! 

During the convention, we'll be a little less active in the comments here on the Kickstarter page. That said, we'll be sure to post some pictures and give you all an update about how the show is going. We will also be posting the print-and-play kit for the Exiles and Partisans deck this Sunday.  

There are many questions popping up in the comments and Kickstarter messages and it is very difficult for us to track. If you have any questions or concerns please contact us at  Remember that since most of us are in Boston there will be some delay in getting back to everyone.

Insight into the New Automated Factions Development
about 1 year ago – Wed, Mar 27, 2019 at 12:58:44 AM

Hello Everyone,

My name is Marshall Britt and I'm the Operations Manager for Leder Games. In addition to my responsibilities managing our finances and logistics, I'm helping develop the new automated factions that we are offering. I'd like to take a moment today to share a bit of what the process entails and what our development sessions tend to include. Our production intern Alex Werner has been assisting in the development and is actively playing games to identify areas where clarifications and improvements can be made. 

It struck me today that not everyone may be aware of the origins of the new automated factions. The design that we are currently developing in the studio is called "The Better Bot Project." The designer, Benjamin Schmauss, and I have been meeting on a somewhat regular basis over the past few months. In talking with Benjamin it's clear that he's incredibly passionate about Root and genuinely wanted to see a more robust solo and automated system implemented. He's guided me through many of his decisions, iterations, and design challenges which has helped streamline our development process greatly. Pictured below is an example of a current bot board: 

The first time I sat down for a session with Benjamin's version of the Mechanical Marquise I was thrilled to find that a single card informed their entire turn. Each of his factions has been extremely satisfying to play and offers an experience that is parallel to a multiplayer game, and most importantly, tells similar stories to those with multiple players involved. A great amount of care has been taken to reduce the player's overhead while maintaining the tension and strategic choice that Root offers. 

The automated factions provide more than just a solo experience! Players can insert these factions into a multiplayer competitive game as well as cooperate games against one or more bots. Alex and I will be working with the editing team from Leder Games in the coming weeks to make sure these factions and the rules follow the Leder Games' house style. If you'll be at PAX East this coming weekend I'll have a copy of Root with the current iterations of the automated factions with me, so feel free to come by the booth to ask for a chance to try them out. Thanks again for your incredible support; we are extremely excited to be adapting "The Better Bot Project" into an official product.
