Imagine an Assassin’s Creed game, super realistic, where the protagonist’s story depends on the player. Like the plot of the game is up to you. Everything happens only ONCE. When Arno dies (For example), like you failed you free running and accidentally fell from the roof. That’s it. He’s dead. There will be a cutscene for his funeral and the credits will show up while a sad song plays right away. Silly.
