Super Mario 3D World is designed to encourage replayability after completing the main story, but it does not include a traditional New Game+ mode that allows players to restart the game with their carried-over progress or enhanced difficulty. Instead, after finishing the main game, players unlock all levels, enabling them to revisit and explore for hidden stars and stamps.

Key Features of Super Mario 3D World Post-Completion:

| Aspect | Details |
|————————-|————————————————————–|
| New Game+ Mode | No |
| Post-Completion Content | Players can collect all hidden stars and stamps, replay levels with all characters to unlock the final stamp, and aim for 100% completion. |
| Additional Content | The Switch re-release includes Bowser’s Fury, a separate open-world adventure that adds new gameplay experiences beyond the original game. |

Replay Incentives:
1. Collectibles: Players can seek out hidden stars and stamps in each level, which contribute to completionist goals.
2. Character Diversity: To unlock certain content, players must complete stages using each of the available characters, adding variety and challenge to the replay experience.
3. Final Stamp Unlock: Achieving completion with all characters culminates in the unlocking of the final stamp, rewarding players for their efforts.

Bowser’s Fury:
The Nintendo Switch version introduces Bowser’s Fury, a new mode that is distinct from Super Mario 3D World. This companion experience offers an entirely different gameplay style in a more open-world format, allowing for exploration and interaction with the environment in ways that differ from the platforming focus of 3D World.

Conclusion:
In summary, while Super Mario 3D World lacks a traditional New Game+ mode, it compensates with replayable content centered around collectibles and character playthroughs, complemented by the additional adventure provided in Bowser’s Fury. Players looking for extended playtime will find plenty of challenges and enjoyment without the specifics of a typical New Game+ format.
