Matthias Rustemeyer is one of the all-time greats at Mario Kart 64. Maybe even the best. Heās certainly the most famous, having dominated the top-tier of its competitive scene for the greater part of a decade. And now heās retiring.
āI completely lost the key value to go on: fun,ā he wrote in a post announcing the decision. A fraught rivalry with the gameās new champion is a big reason why.
Most people outside of Mario Kart 64 speedrunning had never heard of Rustemeyer until YouTuber SummoningSalt posted a video last year documenting the German playerās recent quest to top the leaderboard in all of the gameās no-shortcut world record categories. The video went on to garner more than 2 million views and turned Rustemeyer into a mini-legend among even casual Mario Kart 64 players and general speedrunning enthusiasts. When SummoningSalt announced earlier this week that someone finally managed to secure all 32 world records, many assumed he was talking about Rustemeyer. But he wasnāt. That unprecedented honor instead went to Rustemeyerās longtime rival, Daniel Burbank.
Tense competition is at the heart of any speedrunning scene. It helps spur great players to continually discover better strategies and break new records. For a long time, thatās how Rustemeyer and Burbankās rivalry appeared to function. During his 2018 bid for the coveted 32/32 world record achievement, Rustemeyer came close, winning various records off Burbank only for the latter to work hard clawing them back. Other top-tier Mario Kart 64 players did the same, keeping the elusive goal just out of reach even as Rustemyer remained the clear overall champion.
Then everything changed last summer. While Rustemyer appeared, on paper, to still be the clear champion, in actuality, Burbank was hoarding world record times he had recorded but never officially posted. On June 11 he infamously āunhoardedā all of these times, claiming a number of new world records and shattering Rustemyerās long reign in the process.
Burbank was the new champion. Rusteymer felt betrayed. Burbank wrote a long apology, but neither have communicated outside of live tournaments since.
āDan unhoarded 15 WRs in June 2020 (fooled me and others for 15 months!) and completely destroyed the place I liked to visit almost daily; some players left the scene, many were upset and disappointed, I thought about retirement but kept going after receiving much support and a future hoarding ban with mandatory streaming for Dan,ā Rustemeyer told Kotaku over Discord.
āIt was actually 17 new WRās,ā Burbank told Kotaku over Discord. āMost of them were on tracks where Iād had WR before and the gap to first was very small. Some of them were tracks where there was already a WR tie. A couple tracks I beat the listed WR more than once while I was hoarding. In total there were 22 times that I didnāt release that I had driven.ā
Hoarding isnāt against the rules, but some in the community consider it at the very least bad form.
āThe hoarding did lasting damage to Matthias, and although I gave him some space last year after the unhoard, there was no way I was ever going to be able to make it completely right,ā Burbank said. āI offered the community and Matthias to step away and that any playing I did I would just never report on, but they did not want that either. Although I felt, and still feel, a lot of guilt for what I have done to Matthias and the community, I love this game and wanted to continue playing and finally had time to push my abilities to as far as they could go.ā
In the year since, Burbank continued to grind at an impressive pace while Rustemeyer, deflated and increasingly consumed with other parts of his life, struggled to keep up.

āThe battle we had this year was easily the biggest battle in MK64 history,ā Burbank told Kotaku. āThere wasnāt a jovial competitive spirit to it. though. Iām sure it was personal to him after what happened last year.ā
While the two furiously contested several world records early this year, by July it was clear Rustemeyer didnāt have the same fight in him to challenge Burbankās 32/32 title that he had had years prior when he previously attempted it.
āReal life caught up in May, and I needed a break from the most intense playtime I ever had as other activities became possible again,ā he said. āI came back earlier than planned in July because Dan went from a slight lead to 28 to 29 WRs with insane playtime every day. I didnāt feel the same fire to fight in the summer months. And with his hoarding history, I forced myself to play rather than fully enjoying it.ā
Burbank finally securing the title earlier this week seems to have also been the final nail in the coffin of Rustemeyerās remaining Mario Kart 64 ambitions. Rustemeyer has refused to congratulate Burbank in the days since.
āSome people will call me a bad loser when I refuse to congratulate, but Dan lost all my respect last year. And, for me: Sportsmanship > Gamesmanship,ā he said. āHe feared the fair battle and sneaked to the top so that I couldnāt defend properly, and although he became a very strong competitor itās a loss.ā
While the sun sets on the Mario Kart 64 competitive community for Rustemyer, the way Burbank talks about it sounds more like the dawn of a new era

āThere have been more people playing MK64 in the last year than ever,ā Burbank said, though he admits his actions last summer have had a lasting negative impact. āThe overall mariokart64.com community (including the other Mario Karts) have gotten way more split than ever in the last few years. The unhoard certainly played a role in that, but it has been splitting anyway for many reasons.ā
Still, Burbank is optimistic about the new frontiers of competition that still have room to open up, despite the fact that racers are now battling over fractions of a second on highly optimized courses.
āThereās an upcoming new karter, Xander, that actually got Toadās Turnpike flap WR a couple weeks ago. Then I beat it back, but heās just going to keep getting better and better,ā Burbank said.
For his part, Rustemeyer may be ready to forget, but heās not about to forgive.
āI donāt care if some people will call me a bad loser, Iām a guy who treats fair players with much respect and who doesnāt forget the ones that go against the code of honor to lift their own ego above an entire community with such a rich history,ā he wrote in his retirement message.
Regardless, no one will forget Matthias anytime soon. The forum post was littered with thanks and well wishes.
Wrote one fan, āThanks for all that you have done for the community MR. You will be missed. Cheers to the GOAT!ā
