Which Assassin's Creed game introduced the RPG-style dialogue choices that can alter quests?

Assassin's Creed Odyssey introduced RPG-style dialogue choices that can alter quests.

Released in 2018, Odyssey expanded the series' role-playing structure beyond the systems introduced in Assassin's Creed Origins. Players can select dialogue responses for Kassandra or Alexios, and some choices affect relationships, quest outcomes, and later events. The game also includes branching storylines, multiple endings, gear rarity, level progression, and character abilities.

Origins had already moved the franchise toward action-RPG design with experience levels, loot, and ability trees. Odyssey made player choice a more visible part of the narrative, particularly through conversations and quest decisions. Its large-scale setting is ancient Greece during the Peloponnesian War, where the protagonist's family story unfolds alongside historical events.

Valhalla continued and expanded choice-driven storytelling, which can make it seem like the first example to some players. It followed Odyssey in 2020. Syndicate retained a more traditional structure, while Origins established the RPG foundation without introducing Odyssey's full dialogue-choice approach.
