The Without Number Games: Solo BX Done Right

These are the best solo BX games ever written.

Not “good with a side of generators.” Not “BX if you add Mythic and a notebook.” As they sit, Kevin Crawford’s Without Number line- Stars, Worlds, Cities, Ashes- is already a complete solo engine. Each one can give you years of play without a second book, an oracle supplement, or waiting for the next product to drop. The free editions are real games. The deluxe editions just give you more toys. You can start tonight.

The chassis is pure BX. Six attributes 3–18, d20 combat, the familiar three saves, hit points that matter, and a class or classless path that stays small. Skills sit on 2d6, that Traveller curve that rewards competence without turning every check into a power-gamer puzzle. You already know how to fight. You already know how to die. Nothing on the sheet is trying to be the star of the session.

What makes them solo powerhouses is everything outside the sheet.

The generators do not spit out flavor blobs. They spit out situations. Two tags on a world, a city, an enclave, a ruin. Enemies, friends, complications, things, places. Collide them, and the place already has work. You haven't named the bartender yet, and the session already has shape. Do it twenty times, and you have a sector, a region, a city district, or a stretch of wastes that will still be generating jobs three years from now.

Then the faction turn keeps the world moving when you are not at the table. The groups already on the map grab resources, fight, fall apart, and send trouble whether you asked for it or not. Ignore a court, a corp, a combine, or a mutant enclave for three sessions and the sandbox notices. Most pure BX games stop when the players stop. These do not.

Solo play in a normal BX game is usually “I need an oracle, a hex map, and a pile of random tables I stole from somewhere else.” Here the tables are the game. You roll a world or a neighborhood, note the two tags, run the short faction procedure if you want the pressure to keep building, then play the job that falls out. When that job ends, the map still has heat. You do not have to invent the next thing from nothing. The book already knows how to invent it.

The free versions contain almost all of this. You can hand the PDF around, generate a sector or a city tonight, and start. Deluxe adds thicker toolkits and extra options. It does not unlock the door to play. That choice alone puts them in a different category from most modern OSR products that sell you the chassis and then charge for the parts that actually make long campaigns possible.

They also talk to each other. A spike-drive wreck can land in the Latter Earth. An operator from Cities can bleed into Ashes. Same verbs, different generator. You are not locked into one genre for the life of the campaign. The engine stays small; the universe gets bigger when you want it to.

I have watched pure BX solo campaigns stall because the referee (me) eventually ran out of ideas that felt as sharp as the first ones. The generators and the faction turns remove that failure point. The content does not get thinner the longer you play. It gets denser. Factions remember. Tags keep colliding. Places you left alone keep changing. That is what “years of enjoyment” actually looks like on the page: a sandbox that does not need you to keep feeding it new books.

Most OSRs still sell you a character sheet and hope you will invent the rest. Crawford sold the sheet, then spent the rest of the page count teaching the world how to answer back. Even without a single extra solo tool, they are already the strongest pure BX solo experiences on the shelf. The free ones prove it. The rest is just more ideas, adventures, and infinite play.
