Definitely not. 'Smash Ultimate' is a popular fighting game that is enjoyed by a wide range of audiences, including children. Creating sex - related fanfic not only disrespects the game's intended audience but also can have a negative impact on the game's reputation.
The story mode of Smash Ultimate varies in length depending on your playstyle and how much you explore. On average, it can take several hours to complete.
I think a 'Samus x Captain Falcon fanfic' can be really interesting. It might explore the dynamic between two very different characters. Samus is a strong, independent female bounty hunter from the Metroid series, while Captain Falcon is a cool, fast - driving hero from F - Zero. In the fanfic, they could team up for an epic adventure, perhaps facing a common enemy that threatens both their worlds. It could also delve into a potential romantic relationship between them, which would be quite a unique take given their different backgrounds.
