To everyone who keeps saying that they need to make RoF shorter or play a bunch of games per episode: You're missing the point of the feature. They are going into these games not having played them in years/decades (or ever, probably, further down the line) and they are actually genuinely trying to give each game a fair shake.
They try out every character, learn what kind of moves the game has, and get an ending. If they shorten it, they are either not really learning about the games or have to learn beforehand.
