This was another fantastic video to watch that makes me even more positive on speedrunning. I have never attempted one myself, and probably never will because lazy, but I agree wholeheartedly with him on why they're awesome. Just seeing that OoT speedrunner finally achieving their dream is definitely a story in and within itself, like Hbomberguy said. It's so heartwarming and so unique to games. As some have mentioned above too another YouTuber has done great videos on the speedrunning history of certain games like SMS and Pokemon Red/Blue. Knowing and loving those games as I do it was absolutely fascinating to see how deep people studied them in order to beat them as quickly as possible. Just little stories like how SMS was initially written off upon its launch as a compelling speedrunning game due to its cutscenes and linear progression only for it to become one of the most speedrun games ever and how that one speedrunner got like around *20* random encounters in Mt Moon and still managed a record time were just amazing to hear- even years after the fact.
So yeah great video- love the DK64 humour as well, that game sure is something else.
