The Longest Speedruns EVER

Woah I finally made a Part 2 of this, go check it out: https://youtu.be/9bRpuCZSvhQ

Theoretically, an "all achievements" run of Stanley Parable would be the longest speedrun I can think of. You have to unlock every in-game achievement and then not play the game for ten years. AND part of the all achievements run would include playing Stanley Parable for an entire Tuesday.

Hey! That's my 43 hour long speedrun of Xenogears 100% you mentioned! Thanks for giving the game recognition! Did that run for a 1 year anniversary of me running the game. Was a blast, but I'd never do it again though.

Though it wasn't allowed on the leaderboards due to the fact that nobody is likely to try to best it, the longest single-segment speedrun is actually Animal Crossing New Leaf 100% by Coldeggman, with a time of 638:27:29. Though a substantial part of that time was due to the fact that time spent sleeping was counted in the final time, it still took ~322 hours of actual gameplay to 100% the game. And Coldeggman pretty much played the game with as few breaks as is reasonably possible for something that takes a month IRL to complete, as he played roughly 12 hours on most days of the run. The only runs longer than that that I have seen, are ones that are like Baten Kaitos in which the run is only so long because it requires waiting a substantial amount of time IRL for things to happen, such as Animal Crossing New Horizons Golden Fishing Rod no time travel, which IMO that one really doesn't count since it's just essentially playing the game casually but with a timer running in the background for close to a year.

Not exactly a speedrun but a very long challenge is to get all characters to lvl 99 while still in the first reactor on original FF7; I think the guy that did it maxed out the game timer WELL before it was done and took months to do it.

Honorable mention to speedruns of 'Ring Fit Adventure' - Intended - Max Intensity - 100%, which are not only over 30 hours long, but require unthinkable human endurance.

An all achievements run(maybe excluding the impossible one) for The Stanley Parable would be 5 years, 1 day at the shortest.

Wow, that section about Undertale True 100% was really cool! I bet the runner is a super cool guy. Thanks for including my run!! Very entertaining video by the way. I actually plan on doing True 100% again next month, so that should be... entertaining.

The max cape speedrun that JCW and He Box Jonge are running in Old School RuneScape right now is insane, they're going to end up being ~1000 hour runs

hearing you call 'final fantasy 10' 'final fantasy x' made me laugh super hard every time. i gotta imagine that a star ocean 4 100% run would be 100's of hours long.

As someone who likes speedruns but wants to waste an entire day watching one. This helped.

I still think the most fascinating speedrun that we never got was the Final Fantasy XI 100% achievements discussion for the Xbox 360. The PC version doesn't have achievements, and the Xbox 360 version was shut down years ago. It was a 57 achievement run that had ludicrous requirements, such as getting every class to Level 75, achieving a Rank 100 in synthesis or fishing, completing all missions , and clearing various PVP challenges. People discovered ways to farm a few out, but speedrunners still figured the run would take months. Not weeks, months! Some wanted to try for it assuming they could just keep track of what they normally would be unlocking, but the task was far too daunting. Xbox360Achievements even listed the run would take anywhere from 6 months to over 2 years. Granted, speedrunners would be closer to the months category, but can you imagine said run actually existing?!

small thing for GT4: there are two 100% runs. One is the regular 100% (reaching 100% on the games counter) and True 100% (collect every car, speed run shown in video)

Another extremely long Speedrun I remember was Shadow the Hedgehog True 100%, similar to the Undertale True 100%, the run consists of beating the game on every single route variation, as well as unlocking every Door with 5 Keys hidden in each level and also A Ranking every mission for every stage. The game consists of 326 unique route combinations for the splitting paths between the game's first stage and 10 diferent endings, which the game keeps track of to see which cutscenes to play and in which order in the game's Cutscene Library, 100% in this case would include unlocking every single route to watch in the Library. The only run to my knowledge that has been done was by BlazinZzetti , beating the game in 181 hours, 14 minutes and 47 seconds trought 53 days, this using an exploit to get unlimited Chaos Control gauge and basicly warp to the end of most stages, skipping "get to the goal" missions but risking crashes, which happened around 90 times, he mentions that he has no intentions to do a True 100% Glitchless as this was already too long, he also has no plans on doing this again any time soon, if ever. In order to not have to do a weeks long speedrun every time, the "100%" category ignores the Library for obvious reasons, still requiring the 10 endings at least once, all A Ranks and Doors, Expert Mode and the Final Story, reducing the run to around 7~ish hours, which is still long, but a huge far cry from 181. BlazinZzetti still ocationally runs (both glitchless and not) individual levels, endings and sometimes Expert Mode, also having some 100% No Library runs too btw

Imagine having to sync your speedrun to the moon cycle

You should check out maxing all skill in Old School RuneScape, even the fastest players take almost 2000 hours of in-game time. In addition, people going for fastest max are playing HYPER efficient while playing. And since to many people this is essentially “beating the game” I think it’s a reasonable thing to consider for a list like this :)

I’m really surprised Tom Phantasy’s 301 hour nacht der untoten round 255 run on black ops 3 isn’t on here. Not only is it an immensely hard category but bo3 errors about a month after you initially start it due to entity overflow, so he had to average 12 hours a day straight gaming for a MONTH. Cruppz has a great video on this exact run, it definitely deserves more attention for the amount of effort that went into it.

Wanted to give a shout out to the Shadow The Hedgehog True 100%. It was done once 5 years ago and isn't listed on the leaderboards, but took 53 days IRL and finished at 181:14:47. It requires that you beat the game over 300 times to complete every possible story path, get every secret collectible key, and get the best possible rank in every stage.

Definitely not as long as some of the entries here, but I'd like to give an honorable mention to wh0misds' Pokémon Mystery Dungeon Recruit 'Em All runs. This absolute champ has done Recruit 'Em Alls for Blue Rescue Team (58:03:39), Explorers of Sky (31:42:16), and a marathon REM of Blue Rescue Team, Explorers of Sky and Gates to Infinity totalling 132:11:24 !

I remember watching a Mario Party 4 100% run that lasted around 50 hours. The 2nd place runner had to take a break twice while the game was still running, and as time goes on in the run you can see the runner start to get really out of it, but still in it enough to finish the run. The longest run to a game that should not have taken so long is the last place run of Crash Twinsanity (I think Any%). The user's run clocked in at 24 hours for a category that takes like 13 minutes to run. This was because he left his timer on when he left for something I think. It's hard to say as the full stream I think is gone.
