One of the most impactful scenarios could be when a major character who was brought back by Edo Tensei is released. For example, if Itachi was released, it would have a huge impact on Sasuke. Sasuke's whole perception of the world and his path of vengeance might change completely. Itachi could finally tell Sasuke the truth without any interference from the Edo Tensei caster. Another scenario could be the release of the previous Hokages. They could then use their wisdom and power to prevent further destruction in the ninja world. They might be able to teach the current generation valuable lessons about leadership and peace.
In fanfiction, the Edo Tensei release can create a whole new set of alliances and rivalries. When characters are released, they might not be as beholden to the original caster's wishes. For example, if the Sound Four were released, they could form an alliance with some of the Konoha ninjas against a common enemy. This would add new layers of complexity to the story. Also, the release can lead to a change in the power balance. If a powerful Edo Tensei - controlled character like Kisame is released, he could either become a great asset or a huge threat depending on his motives.
