Where the main game runs a whole crew, this one hands you the captain's chair and a blank log to fill in: you create an original character and use the book's guidance and random tables to generate episodic Star Trek stories, one log entry at a time. Do you think a space-based solo TTRPG on mechanics you already like would escape the garden's grasp? You would be terribly wrong. ## Setting The same franchise promise, pointed right at a single character. Play in any era of Star Trek, from the 21st century to the 32nd, as any kind of character — not just a Starfleet captain, though that's the headline pitch. You build (or randomize) your own starship or starbase, and then each session runs as a mission logged in the captain's voice. The book carries a Star Trek primer covering society, technology, and the eras of play, so you don't need anything but the one rulebook to be off the dock. ## Mechanics It's the **2d20 system** streamlined into a solo engine — you roll two twenty-sided dice under a target built from an attribute and a skill, count successes, and read them against a difficulty, exactly as in the main game, with the **Fill values** and Momentum economy tuned for a lone player rather than a table. The solo structure leans on the book's **100+ random tables and storytelling matrixes** — alien worlds and polities, allies and enemies, mission themes, maintenance downtime, and the rest — to drive a story that "promotes drama in a safe space." The 2026 edition's ruleset incorporates the collected errata since the first book, so it plays as the current, cleaned-up version of the game. ## Editions - **Captain's Log (First Edition)** — **2023**, Modiphius. *In the library* (the DS9-cover copy, plus its supplemental and sheets). - **Captain's Log (2026 Edition)** — **2026**, Modiphius. *In the library* (the *Solo RPG 2026* core + supplemental). A new edition with a brand-new cover and an updated, errata-incorporating ruleset — the content is the same game, freshly tuned. ## Supplemental The **Captain's Log: Supplemental** is the box's bonus PDF — essentially the book's deleted Chapter 7 plus the *Lower Decks* ships, shipped to fill the gaps a tight page count and pre-release licensing left behind. It carries a large set of **Mission Prompts**, each a ready-made solo seed with a title, an opening log entry, possible encounters, prompt questions, and suggested conflicts — the content cut late in development to keep the book to a manageable size, now handed back to you — and the **Star Trek: Lower Decks starship spaceframes**, which couldn't make it into the print book because the *Lower Decks* rights were secured after production wrapped. *In the library* (a copy accompanies both the 2023 and 2026 editions). ## References - [Captain's Log — Solo Roleplaying Game (2026 Edition) — Modiphius](https://modiphius.net/en-us/products/star-trek-adventures-captains-log-solo-roleplaying-game-2026-edition) - [Star Trek Adventures: Captain's Log — Modiphius collection](https://modiphius.net/en-us/collections/sta-captains-log) - [Captain's Log review — Stevivor](https://stevivor.com/reviews/star-trek-adventures-captains-log-solo-rpg-review/) > [!note] Editor's Note > > One Weird Fact: The Modiphius 2D20 System really reminds me of **[[Ironsworn]]** and **[[Ironsworn - Starforged|Starforged]]** in a weird way. > > You commonly roll 2D10 versus a stat plus any adds and compare the total to each of the dice independently in order to generate a strong hit, a hit, or a miss. > > 2D20 effectively works the same way, except with a larger linear range, which means that small differences don't mean quite as much. > > I'm not sure I'm completely on board with the way the stats fall out, but I don't hate it. > > As for why I picked up **Star Trek Adventures: Captain's Chair**? > > Do you think that any kind of space-based solo TTRPG with streamlined mechanics of a sort I already like would escape my grasp?
