The LitRPG subgenres, explained.

Cultivation, dungeon core, cozy, kingdom-building, VRMMO, system apocalypse. What each shelf actually promises, and which one fits what you already like.

The genre has a naming problem, and it costs you a month.

Someone tells you they love LitRPG. So you go find LitRPG. What you come back with might be a six-hundred-page war story about a man being tortured into competence, or it might be about a duck farmer.

Both are correctly labelled. Both have stat blocks. They've got almost nothing else in common.

And if you wanted the duck farmer and bought the war story, you just spent three weeks on a book that was never for you, sold to you under a name it shares with the one that was.

So this is the map. Eight shelves, what each one promises, the book that defines it, and who should walk past.

Three questions sort most of it. What pace do you want, what stakes can you stand, and what are the numbers for: a scoreboard, or a stress test?

You're buying a pace. Which means the wrong shelf costs you a month instead of an afternoon.

New here, and none of these words mean anything yet? Start here instead and come back.

Been arguing with someone about whether any of it counts as progression fantasy? That argument has its own page.

1. System apocalypse

The world ends on a Tuesday and turns into a game. Everyone alive gets a stat screen in the same moment, most people die in the first week, and the story's about what a person becomes under a scoring system nobody consented to.

Dungeon Crawler Carl is the anchor, and it's the funniest and the cruellest thing in the genre.

Walk past if you want the world to still be there in book three.

This is the biggest shelf and the one most people land on first. It's got its own full page here, and the read-alikes are over here.

2. Cultivation and xianxia progression

A ladder with named rungs, and a protagonist who climbs every one of them in front of you.

Advancement is the plot. The pleasure's structural: you can see the next tier from where you're standing, you'll get there, and it'll cost something specific.

Cradle is the anchor. Twelve books, finished, which makes it the rarest thing on this list — a complete long series you can read end to end knowing the author landed it.

Walk past if you want a protagonist who's already good at something. This shelf will frustrate you for two hundred pages before it pays you back, and that's the deal it's offering.

The head-to-head against Carl, if you've only got room for one, is here.

3. Dungeon core

You're the dungeon. The thing the heroes come to clear.

You start as a stone and a scrap of will in a hole in the ground, and you spend the book spending points on corridors, traps, monsters and ecology while adventurers walk in and die on your architecture.

Dungeon Born opened this shelf and it's still the cleanest way in.

Worth thirty seconds before you buy anything.Dungeon Crawler Carl is a person going into a dungeon. Dungeon core is the dungeon.

It's the most common mix-up in the genre, and buying one when you wanted the other leaves you baffled by chapter two.

Walk past if you need a human face to attach to. Your protagonist is a building. That's either delightful to you or it isn't, and you'll know inside a chapter.

Why it's having a moment: it's the closest prose gets to a management sim. You're never really at risk, so optimisation does the work combat tension usually does, and optimisation turns out to be enormously moreish.

4. Cozy, slice-of-life and farming

A system, a small place, and nothing trying to take it from you.

Somebody moves to a valley, gets a stat screen, and spends it on crops, cooking, animals, a shop, a village. The numbers still go up. Nobody gets tortured.

Beware of Chicken is the anchor. It started life as a cultivation parody and became the defining cozy work in the genre by taking the farming seriously and the martial world lightly.

Walk past if escalation is what you read for. If you need each book to raise the ceiling, cozy reads as a run of pleasant afternoons where nothing's at stake. That's the entire product.

This shelf is growing faster than any other right now, and I think that's because a lot of people arrived at the genre through burnout instead of through fantasy. Cozy works because nothing in it is trying to take the farm from you. It reads like a Saturday.

It's also the worst-served shelf on the recommendation lists, most of which are apocalypse-first and stick cozy in a footnote at the bottom.

If you want the softest landing in the genre, this is it. It's where I'd put a nervous friend.

5. Kingdom-building and base-building

You get a settlement instead of a sword. Walls, granaries, populations, trade routes, a workforce with opinions.

The stat screen's a management console and the antagonist is usually logistics.

Bastion is the anchor, for the version where the base is under real pressure and the building is a defence.

Walk past if a chapter of supply-line arithmetic sounds like homework. For the people it's built for, it feeds the same appetite a factory-builder game feeds, and that's an appetite prose almost never gets to serve.

6. VRMMO and trapped-in-the-game

The original shape. Somebody logs into a game and either can't log out or doesn't want to.

The stat screen's diegetic here, because it's literally a game interface. Cleanest justification for the whole apparatus anyone's managed.

Awaken Online is the anchor. It took the shelf seriously after it had gone stale, and put a genuinely uncomfortable protagonist in it.

Walk past if you want the stakes to be real. In a VRMMO, dying costs you experience.

One honest note. This is the oldest shelf and it's aged hardest. VRMMO aged because the real thing arrived and turned out to be less interesting than the fiction had promised, and the genre's centre of gravity moved to systems that come to you instead of systems you log into.

The good ones are still very good. There are just fewer new ones.

7. Military and squad

A unit, a chain of command, and numbers that work as force multipliers. Competence porn with a stat sheet.

This one's got its own post, and I'd rather send you there than compress it here.

Walk past if the appeal for you is a lone person getting powerful. A squad book keeps interrupting that to check on five other people.

8. Crafting and non-combat class

Your protagonist's a blacksmith, an alchemist, an enchanter, a cook. Advancement comes from making things well, and the fights, if there are any, belong to somebody else.

Life Reset is the anchor, for the version where the crafting carries the book.

Walk past if you want a fight scene. You may go three chapters without one.

This is the quiet end of the genre and it overlaps heavily with cozy. The distinction worth keeping: cozy is about the place, crafting is about the work.

A crafting book can be tense. A cozy book usually declines to be.

One of these shelves is mine. Here's which, and why I put it last.

Where mine actually sits

The Integration Era is a science fiction series about a world remade by an alien system nobody asked for. It switches on across all of known space with no warning and starts measuring every person alive: six attributes and a designation, a verdict on what you are that it then sets about making true. Score high in Frame and it hardens your bones until the number's honest.

By premise, that's shelf one. I could stop there, and it'd be a slightly dishonest place to stop.

The whole claim, and it's one claim: the apocalypse never arrives.

The system switches on, a hundred years go by, and the scoring settles into infrastructure. Insurance rates, hiring, custody hearings, what a dock supervisor's allowed to certify. Once it's infrastructure, you can live an ordinary life inside it, which means the shelf gets picked per story instead of per series.

That's unusual, and here's why it happens. In most of this genre a series and a subgenre are the same object, because there's one protagonist climbing one ladder and the ladder decides the shelf. The Integration Era has one system and a lot of ordinary lives, so the shelf moves when the protagonist does.

So let me sort my own catalog with the questions this post's been using.

If you came for the ladder — visible rungs, a real cost per rung — start with First Contact. Kes Marrow has carried one flagged stat for four years without it moving. One night he hikes past the colony fence to a Flux rift, with his two best friends and a theory, to make the system look at him again.

Six chapters, complete, free. Part one runs about seven minutes, so you'll know quickly whether the voice is for you.

If you came for the squad, shelf seven: Zero Drift. Nara Tholren spent three years alone on a survey world learning to wait, then enlisted. What follows is basic training, fireteam rotations, and a multi-squad exercise where three corporations turn up with three different sets of rules of engagement.

Load Bearing is the same shelf at close range: five operators, one extraction, and one of them holding a junction alone so the others can transit.

And Signal Zero is the soldier standing closest on the morning the whole thing switched on. It's the only genuine system apocalypse I've written.

If you came for the ordinary life, shelf four: Carried Forward is eleven years at a company and a woman who's never once checked her own metrics. Unopened is a mother watching her son's overlay come online at twenty-two months.

Nothing's trying to take the farm in either one.

And one that's off the map.Infrastructure is an analyst writing a report her office has already decided the shape of, who finds that the system's performing exactly as designed. If there's a shelf for that, this post didn't name it.

If you came for the volume turned up, the read-alike list is the better door, and I'd rather you took it. There's also a whole post on the grounded end of the genre that recommends four other people's books before it mentions mine.

Kes turns up again a few years older in Engagement Criteria, which is going out a chapter at a time right now.

Sign up free and the new ones reach you the day they land, along with every post. The audio version of this one's on the podcast if you'd rather have it in your ears on a walk.
