Dungeon Crawler Carl hits 14 million copies, and Matt Dinniman kept his ebook rights

Here's the story every indie author needs pinned above their desk: a litRPG series about a man and his cat surviving a deadly game show, which started out indie, has sold over 14 million copies, hit both the Amazon and New York Times bestseller lists, and landed a live-action TV deal with Seth MacFarlane — yes, the Family Guy Seth MacFarlane — attached as a producer with showrunners on board.

That's Matt Dinniman's Dungeon Crawler Carl series. And according to Written Word Media's Ricci Wolman and Ferol Vernon, who just launched a new podcast case-study series digging into how indie authors "make it big," Dinniman's path started small: two people at a convention booth, building an audience one reader at a time in a genre — litRPG — that neither host had even considered mainstream before this book.

Here's what actually matters for you this week. Dinniman didn't get here because litRPG was a safe bet. It wasn't. Wolman says it's "not a genre that I read," and put it next to Ready Player One as basically the only other bestseller comparison she could think of. He started out indie, and a Random House deal came later, for print rights only, with Dinniman keeping his ebook rights. That's the headline fact worth sitting with: the readers said yes first. Dinniman built the audience, and the bestseller lists followed.

So what do you do with that if you're indie and grinding? First, stop waiting for a gatekeeper's permission slip before you commit to your weird, specific, hard-to-categorize book. The lesson from this case study, per Vernon, is explicitly built to apply "regardless of what you're writing." Second, know that Written Word Media says this is the first in a series — more case studies on indie authors who broke out are already in the works. Watch for those. They're building a playbook, one author at a time, and you don't have to guess at the lessons alone.

Third — and this is the practical bit — if you're serious about learning from authors who've done this, go find your people in person. Wolman and Vernon are both heading to Author Nation in Vegas this November, and Written Word Media will have a booth all week. NINC is happening this month too. Conferences aren't just travel expenses; they're where you find the community and the specifics that a podcast summary can't give you.

My take: this isn't a story about litRPG. It's a story about what happens when an author refuses to shrink their book down to fit someone else's list. Dinniman didn't get smaller to get picked. He got bigger until he couldn't be ignored. Watch for the next case study from Written Word Media — that's where the repeatable lessons will start to show up.

Correction, 7 October 2026: An earlier version of this story said Dungeon Crawler Carl was built with no publishers and was passed on by traditional publishers. Matt Dinniman started out indie and later signed a Random House deal for print rights only, keeping his ebook rights. We have corrected the story.
