Dylan Dylan “CavemanDCJ” Jock built his reputation in the early 2010s as the kind of runner who went looking for the strangest corners of the PlayStation and beyond. He gravitated toward games with bad voice acting, broken physics, or tiny cult followings, then took them seriously enough to route, grind, and showcase them on the biggest stages the speedrunning scene had at the time. His body of work is not about chasing the most popular leaderboards. It is about giving obscure and sometimes deeply questionable games a place in the historical record.
Today he is best remembered for two things. One is a slate of polished record runs on the old leaderboard and video hub of Speed Demos Archive. The other is a single marathon run of a pink haired platformer that produced one of the most quoted sentences in marathon history and quietly reshaped how a charity institution handled its commentary couches. Together those pieces make his career a useful snapshot of the bridge between the Speed Demos Archive era and the later marathons of Games Done Quick.
Building a Niche in the SDA Era
When the Speed Demos Archive staff compiled a runner index in the mid 2010s, Dylan “CavemanDCJ” Jock appeared there with a short but very specific list of published runs. The site credits him with any percent single segment records in three different games: T.R.A.G.: Tactical Rescue Assault Group – Mission of Mercy on PlayStation with a 56 minute 49 second run in April 2013, Tomba! 2: The Evil Swine Return with a 1 hour 14 minute 35 second run in July 2014, and the unlicensed Sega Genesis platformer Pocket Monster II with a four minute 13 second clear on Easy that same summer.
Those choices alone tell a story. None of these games were obvious speedrunning staples. T.R.A.G. was a forgotten late 1990s action title with tank controls. Tomba 2 was a cult platformer that many viewers remembered fondly but rarely saw beaten in one sitting. Pocket Monster II was not even an officially licensed game. In the author comments attached to these runs, Jock framed that oddness as part of the appeal. For T.R.A.G. he openly called it an obscure title that most people knew, if at all, for its terrible voice acting, then explained how he learned to wrestle with the four playable characters and the clumsy control scheme in order to keep the run moving.
In other words, he did not just pick weird games. He approached them with the same kind of mechanical breakdown and route planning that other runners were bringing to more famous series. That combination of taste and discipline would carry over when he moved from SDA submissions to marathons.
Bootlegs, Bad Voice Acting, and Clever Routes
T.R.A.G. is a good example of how Jock treated marginal games as serious projects. The game blends fixed camera angles and pre rendered backgrounds with four different characters who each have their own movement and combat strengths. His run exploits those differences aggressively. In the commentary he describes why he swaps almost immediately to Michelle, whose movement speed makes her the main workhorse for much of the story, and how he uses Rachel’s small frame to reach spaces other characters cannot. Burns, the heavy, appears only when absolutely necessary. For all the jokes about the voice acting, the writeup emphasizes that movement and boss consistency matter most because there are few glitches to lean on.
Pocket Monster II represents an even stranger case. The game is a bootleg Genesis platformer that borrows characters and imagery from Pokémon without authorization. On its SDA page, Jock describes how he first encountered it in a large blind race and became fascinated enough to buy real hardware and a cartridge so that his times would not be limited to emulation. He catalogues a series of bizarre mechanics, from the way Pikachu moves faster to the left than to the right to the “air jump” that occurs when the character takes damage or stomps an enemy. He even jokes that sometimes the protagonist’s hitbox seems to break free of the sprite entirely, “hunting down enemies mercilessly.”
Those comments made such an impression on the Speed Demos Archive staff that they quoted them in a front page news post introducing the Pocket Monster II run to the wider community. In an era before social media clips dominated the conversation, that news entry and the accompanying video preserved both the mechanics of the game and the tone of a runner who knew how to balance technical description with self aware humor.
Tomba 2 was the most ambitious of these projects. On his SDA page Jock describes the game as essentially resistant to sequence breaking because of how tightly progress is locked behind completing tasks and collecting items in a fixed order. He notes that even if someone found a way to skip a section, the story logic would usually force the player to go back and complete it anyway. To make the run faster despite that rigidity he popularized a movement trick he called “boost jumping,” where the player attacks and then jumps in quick succession to gain extra forward momentum.
For all that work, he admitted that the run consisted largely of mashing through unskippable cutscenes and long dialogue sequences. In his conclusion he wrote that he was satisfied with 1 hour 14 minutes, believed a 1 hour 13 minute time was technically possible, and was not eager to keep grinding the game unless a significant new trick emerged. That mixture of affection, frustration, and clear eyed route analysis would define how many viewers came to know him when Tomba 2 finally appeared on a marathon schedule.
Summer Games Done Quick 2014 and a Viral Line
Tomba 2 reached the marathon stage at Summer Games Done Quick 2014 in Denver. The official run index lists “tomba 2” with CavemanDCJ as the runner in the mid morning block on June 25, with a scheduled estimate of one hour and twenty six minutes. The GDQ YouTube upload records his final marathon time as 1 hour 17 minutes 27 seconds, a strong showing against that safe estimate and only a few minutes slower than his best recorded SDA run.
The run itself followed the contours of his SDA route. He used boost jumping to manage Tomba’s movement through the game’s side scrolling and light platforming sections, made deliberate choices about when to pick up optional items that would pay off later, and spent considerable time talking through what he was doing moment to moment. For spectators who had never seen Tomba 2 finished, let alone run efficiently, it was an unusually detailed tour of a game that sat just outside the usual PlayStation canon.
What made the run famous, however, was not a trick or a skip. Midway through the broadcast, one of the couch commentators repeatedly mocked the game and derailed the commentary with jokes at its expense. In response, Jock turned to the couch and delivered a now famous sentence asking that they be quiet so that he could focus on explaining and playing. The clip of that exchange, especially the line “I would really prefer if you would be quiet,” spread quickly across forums and social media and is still widely shared in highlight compilations of awkward GDQ moments.
The episode did not simply generate a meme. Community discussion on Reddit in the months after the marathon noted that the incident prompted Games Done Quick staff to tighten their policies on who could sit on the couch and how commentary was coordinated, shifting more authority toward the runner when it came to deciding who would join them on microphone. A later academic paper on speedrunning charity marathons by James Sher and Austin Su used the Tomba 2 run as an example of tensions between entertainment, donations, and respecting the runner’s expertise, describing it as “an infamous moment” when a couch member’s mocking remarks crossed an unspoken line.
Over the years the Tomba 2 run has been cited in mainstream retrospectives on Games Done Quick as one of the defining moments in the series, not because of technical complexity but because it encapsulated the social dynamics of a live marathon couch. A Yahoo feature on memorable GDQ clips, for instance, highlighted Jock’s quiet but firm pushback as the turning point in a segment that would otherwise have simply been remembered for its discomfort.
For Jock’s legacy, that means the Tomba 2 run functions as both a showcase of his routing work and a case study in how runners claim space for their games on a crowded stage.
From Noitu Love 2 to Gunners Heaven
Tomba 2 was not his only contribution to SGDQ 2014. That same marathon featured his run of the indie action game Noitu Love 2: Devolution, recorded in 27 minutes 35 seconds with fast paced commentary that showed he was equally comfortable with modern PC titles and retro console fare. Together the two runs positioned him as a specialist in games that rewarded constant movement, aggressive routing, and the ability to explain busy screens without losing composure.
Four years later he returned to the main marathon stage with what would become his other signature performance, an any percent run of Gunners Heaven at Awesome Games Done Quick 2018. The official schedule lists the game in the early morning hours with a 31 minute 31 second estimate, which he matched almost exactly on stream.
Gunners Heaven, known in some regions as Rapid Reload, is a frenetic side scrolling shooter often compared to Contra and Gunstar Heroes. It never saw a North American release, and for many viewers the AGDQ showcase was their first exposure to it. A recap article of day two of AGDQ 2018 singled out Jock’s run as a highlight, praising his dry humor, relaxed attitude, and ability to keep the commentary both informative and funny while the screen flooded with enemies and projectiles.
On Reddit, a thread about the run from that week called it one of the marathon’s standout moments and joked that he was “the best player of the game (he checked).” The praise focused not only on his execution but on how he explained the obscure mechanics, enemy patterns, and route choices in real time, turning a little known Japanese PlayStation shooter into something spectators could follow and appreciate.
Taken together, the Tomba 2 and Gunners Heaven marathon appearances show the thread that runs through his catalog. Jock chose games that most players never finished or even heard of, then used the marathon stage to give them context and structure.
A Name in Credits and a Quiet Exit
Outside of the SDA and GDQ ecosystems, Jock’s handle and full name appear in a handful of other places that trace the growth of speedrunning’s influence. The GameFAQs transcript of the credits for the indie platformer Iconoclasts lists “Dylan ‘CavemanDCJ’ Jock” among its credits, suggesting that his involvement with the community extended into testing, feedback, or promotional support for modern action games as well.
Speed Demos Archive’s runner index and news posts preserve his contributions in a more formal way. Beyond the three main published runs, they include his name in a long list of runners whose work defined the site’s catalog through the mid 2010s.
In later years, though, his public presence diminished. A 2023 Reddit thread marking “ten years since that Tomba 2 speedrun” remarked that he had “pretty much disappeared from the internet over the past few years,” with posters mostly expressing hope that he was doing well and appreciation for the runs he had left behind. A small Twitch channel under his familiar handle exists but has only a modest follower count and little visible activity compared to the peak marathon years.
For a historian, that gap is part of the story. Speedrunning has always had figures who shine for a few years in a particular scene and then step away, leaving behind a handful of videos, forum posts, and author commentaries as their main record.
Legacy in the Archive
Jock’s legacy is not defined by a long list of world records across flagship franchises. Instead it rests on three intertwined contributions.
First, he treated marginal and even disreputable games as worthy of full speedrunning treatment. By routing T.R.A.G., Pocket Monster II, and Tomba 2 with care and documenting those routes in detailed SDA writeups, he preserved knowledge that might otherwise have evaporated around a few stray forum posts and low quality videos. Those pages now serve as primary sources for anyone attempting to reconstruct how early 2010s runners approached strange or unpopular titles.
Second, he helped demonstrate how powerful the marathon stage could be in reframing games. His Tomba 2 and Gunners Heaven runs show that a single well executed, well explained performance can define how a wider audience remembers a game. The Tomba 2 run, in particular, also became a reference point in conversations about how to balance couch banter, runner authority, and respect for the work that goes into making a difficult run possible.
Third, his presence in places like the Iconoclasts credits hints at the more diffuse influence of runners on game development and promotion. The same skills that made him a compelling marathon commentator, namely an eye for mechanical nuance and a willingness to dissect systems out loud, made him a useful collaborator and tester for designers trying to understand how expert players would approach their work.
In that sense, Dylan “CavemanDCJ” Jock stands as an example of a certain kind of speedrunning figure from the SDA to GDQ transition era. He did not build a massive personal brand or chase every new platform. Instead he left a smaller but sharper legacy of runs and commentaries that continue to circulate long after he stepped back, reminding viewers that even the strangest games can find a place in the historical record when someone takes them seriously enough to run them well.
