I know Undertale's rallying and Undertale in general was the story of this contest, but to me this match was the best match in round 3. Not only did Super Metroid finally get over the Mario hump by demolishing Galaxy in round 2, it was one ASV away from actually beating a Zelda game. And not just any Zelda game, but our Game of the Decade in Majora's Mask. I'm convinced that Super Metroid could have won this match if people didn't want Game of the Decade validated so hard, but I can understand why Majora's Mask was the rooting interest here. The anti-Brawl sentiment and people just loving Game of the Decade in general outweighed rooting for the cool upset.
