I loved some of the other entries to the Duet RPG Jam, but I've got to be honest… Agent of the Throne is on another level.
We couldn't playtest this entry, but that's just because we didn't have enough time to do it justice. This is some commercial quality content. I'm surprised that it was submitted to a 3-days jam, and I can only assume that it's based on previous work by Toastmortem. (To be clear: that is OK and not forbidden by the rules.) It's also immaculately edited, with great pagesetting and nice, if sparse, art.
Agent of the Throne is a meticulously thought out OSR for one player and one DM. It has detailed rules for building a "retinue"–a party of NPCs following and supporting the player. That's a brilliant idea to make up for the lack of a party of adventurers.
Throughout the rulebook, you can see glimpses of an interesting setting. In pure OSR fashion, the setting is communicated less through evocative prose and more through the rules themselves. It's just enough background to get your creative juices flowing, without being overbearing. The gameplay itself is a brilliant mix of investigation and combat, supported by smart ideas such as the "Subtlety" rules. The authors even give advice on how to structure a compelling narrative.
Agent of the Throne is a rich "duet" RPG that begs to be played. Kudos to the authors! This is the kind of stuff makes me want to organize another Duet Jam tomorrow.
