The duration of the story in Pokemon Sword and Shield isn't fixed. If you just rush through the main plot, it might take 15-20 hours. But if you take your time, do all the extras, and explore thoroughly, it could easily go up to 40 hours or more.
You can start by completing the main story and then accessing special post-game quests or events. Some might be unlocked by achieving certain milestones or meeting specific conditions.
Well, the duration of the Pokemon Shield story is not fixed. It depends on your playstyle. If you rush through the main quests, it might take around 20 hours. But if you take your time, do side quests, and explore thoroughly, it could stretch to 30 hours or more.
In Pokemon Shield for the story, you could build a team around Snorlax. It has high HP and can be a tank. Add to that Alcremie which is a Fairy - type with some nice moves. Mr. Rime, an Ice / Psychic type that can be quite strategic in battles. Dubwool, an evolved form of Wooloo, is stronger and can hold its own. And for a fast attacker, Ninjask which is a Bug - type with extremely high speed.
Well, I'd say for the story in Pokemon Shield, you could go with Sobble, Grookey, and Scorbunny as your starters. Then add some like Duraludon which is a Steel / Dragon type and can handle a lot of different types. Also, Grimmsnarl, a Dark / Fairy type that's quite tough in battles. And Appletun, a Grass / Dragon type that has some useful moves and good bulk.
One idea could be to focus on a new trainer's journey in the Galar region. They could start with a unique Pokemon not often chosen, like a Galarian Zigzagoon, and face various challenges that the game doesn't cover. Another could be a story about the backstory of a Gym Leader, perhaps their rise to power and the secrets they hold. Maybe a fanfic where Pokemon from different regions end up in Galar and how they interact with the local Pokemon and trainers.
The length of the post-game story in Pokemon Shield isn't set in stone. It depends on your playstyle. If you rush through, it might only take 5-10 hours. But if you take your time, do side quests, and battle other trainers, it could stretch to 20 hours or more.
In Pokemon Sword, Sobble is a great choice for the story. It's cute and has a good evolution line. Its final form, Inteleon, is very powerful and can be quite useful in battles throughout the story. Also, Grookey is a good pick. It evolves into a strong and cool-looking Rillaboom, which can handle many of the challenges in the game's story.
