One speedrunner has 100% completed nine 3D Mario games in a single, sleep-deprived, 44-hour marathon.
'Multiple Mario games' is a speedrun category dating back several years, featuring specific runs with names like 3D Mario 602, a challenge where you need to collect 120 stars in Super Mario 64, 120 shines in Sunshine, 120 stars in Galaxy, and 242 stars in Galaxy 2. Top runs in this category can take nearly 20 hours, and breaks - even to eat and sleep - are counted as part of your time.
Then you've got 3D Mario 1862, which requires you to do everything in 602, plus get all 380 green stars in 3D World and all 880 moons in Odyssey. The top run here is just under 32 hours, and runner Odme_ submitted it with this comment: "Insanity. Never doing this again lol."
Another runner, named KingJ, currently holds the second-place record in the 1862 category, with a time just under 35 hours. Rather than simply go for another attempt, he was inspired to go even further with the first (and "probably only") 3D Mario 2405 run, which includes all the challenges above, but adds 150 stars in Mario 64 DS, 293 medals in 3D Land, and 100 cat shines in Bowser's Fury.
"I've been speedrunning for around six or seven years," KingJ tells GamesRadar+. "I had done multiple 1862s in the past since 2020, and held world records for it extensively. About a year ago, someone named CreateSource made up the idea of 2405 and I thought it was a smart and cool expansion off of 1862." So KingJ made plans to take on 2405 - once he picked up the pricey 3DS mod needed to stream his runs of 3D Land.
KingJ tells us that he's "spent the last four years grinding all the different categories on and off and improving upon all of them. Once I announced a date for the 2405
