The Guinness World Records has awarded Library of Ruina with the world record for “longest videogame campaign/story.” The previous award holder was Persona 5 Royal.
Guinness outlines the award on its site:
Deck-building, turn-based RPG Library of Ruina (Project Moon, 2021) has a main campaign playtime of around 113 hours, as of June 2026. That’s a thumb-numbing 12 hours more than previous record holder Persona 5 Royal (P-Studio, 2019).
Library of Ruina is a direct sequel to horror management sim Lobotomy Corporation (2018). There’s also a third game, Limbus Company, an action RPG released in 2023.
Library of Ruina is available now on Nintendo Switch, PlayStation 4, and PC. Final Weapon reviewed the game and gave it a 3.5/5. We described it as “both a fantastic and frustrating experience. A twisted narrative and complex mechanics make for what could be a cult classic. Unfortunately, the lack of a natural difficulty curve as well as some awkward UI issues will make this game significantly less appealing to some. Overall, it is worthwhile, providing you have the time to fit it in your schedule.”
The Steam page describes Library of Ruina as follows:
“May you find your book in this place.”
Become the owner of the Library and receive your guests.
Your librarians will fight for the Library.
Combat between the guests and the librarians breaks out as if it were on a stage.
Defeated guests turn into books, and the Library grows onward.
A good book will allow you to invite new guests with greater secrets.
Amass a collection of books and explore the secrets of the City.
And eventually, get your hands on…
The one singular, perfect book.
