I don't know why Narcissa thinks competitive gaming is the same as speedrunning. With speedrunning you sink loads of time into something until you are mechanically better than other people. It requires little talent or creativity for the most part, only endless repetition in an unchanging scenario (excluding new tricks being learned). With fighting or competitive games you require some level of skill for the game, and a lot of creativity/reading into the meta and opponent that goes beyond just autistic button mashing. Narcissa is not capable of this, she wasn't as Cosmo (he was good but not level high level at smash), and especially isn't now.
