The certified playtime is about 113 hours, which the record puts 12 hours above Persona 5 The Royal. The game is available on PC via Steam, Nintendo Switch, PS4, Xbox Series X|S and Xbox One.","whyItMatters":"The record rests on a clear-time figure whose method Guinness does not specify, and HowLongToBeat's 113-hour Main Story entry for Library Of Ruina matches it, so the title measures reported playtime rather than a verified standard.","webCardHtml":"\u003cp\u003eGuinness does not publish how it calculated the 113 hours. The figure lines up with HowLongToBeat\u0026#39;s Main Story average for Library Of Ruina, and the 101-hour Persona 5 The Royal entry matches the 12-hour gap the record describes.\u003c/p\u003e\u003cp\u003eThat comparison has limits. HowLongToBeat lists idle games such as NGU Idle at 1591 hours and Melvor Idle at 1394 hours, and the Football Manager series also runs past 113 hours. ProjectMoon\u0026#39;s earlier Lobotomy Corporation sits at 58.5 hours on the same site. About 94% of roughly 41,000 Steam user reviews for Library Of Ruina are positive.\u003c/p\u003e","blueskyPost":"Guinness measured Library Of Ruina's story at 113 hours, but ProjectMoon's game is a deckbuilding battle system first. Length here is a consequence of difficulty, not padding.","twitterPost":"Library Of Ruina's 113-hour Guinness record counts a story gated behind hard deckbuilding fights. The hours are earned, not scripted.","threadsPost":"Library Of Ruina's Guinness title measures 113 hours of story, but ProjectMoon built that length around a punishing library battle system. The record counts hours a player has to fight through, not cutscenes they can sit back for, which makes the number a difficulty stat as much as a script length.","newsletterBlurb":"ProjectMoon announced that Library Of Ruina has a Guinness World Records title for the video game with the longest campaign or story, certified at about 113 hours. That is 12 hours past Persona 5 The Royal.
