Assassin's Creed Odyssey was the first game in the series to let players have a choice in the narrative. The massive game had branching storylines based on major and minor decisions. Both the side quests and main quests had difficult, morally complex decisions that caused different reactions from characters and the world.

Odyssey is a huge game. It's possible to log in 80 hours and still have content to finish.  Tons of decisions are made in one playthrough. Some are less important than others, but others have a major impact on the game. That said, let's have a peek at some of the toughest choices in the game and what impact they'll have on your playthrough.

10 Bravely Ran Away: Give Morys The Armor Or Keep It

A man named Morys was tasked with killing the Minotaur but was too much of a wimp to follow through. The Misthios is tasked with finding a set of armor and an axe so Morys can at least look like he killed the Minotaur to save face in front of his people.

After the player goes on an unnecessary killing spree to receive the items, they have to either give them to Morys or keep them for themselves. The player can keep the powerful items, but Morys will still feel like a failure. On the other hand, the Misthios could lose out on some loot and Morys would gain some confidence.

9 Monger Down: Kill The Monger Publically or Quietly

Monger from Assassin's Creed Odyssey

The player has to decide to kill The Monger, a vulgar cultist,  inside a cave or in an amphitheater. This is a deceivingly important decision for the main story. Brasidas wants The Monger killed quietly to avoid unnecessary politics while Anthousa wants to make a show of his death.

If the player decides to kill the Monger in the cave, then a character named Lagos can be persuaded to leave the cult of Kosmos and help you down the line. It also leads to a happier ending that's filled with friendships. If the Monger is killed in public, then the player is forced to kill Lagos and lose a valuable ally.

8 A Bloody Feast: Who is the Cultist?

Assassin's Creed® Odyssey_20181126114452

One of the two Spartan kings is a cultist, and it's the player's job to figure out who. In an LA Noire style quest, the Misthios has to gather evidence and prove that one of the kings is, indeed, a cultist. The difficulty this time around does not come from a moral choice, but choosing the right option.

If Lagos is still alive, then he will give you the necessary evidence to make an informed decision. Pausanias is the right choice. He will be kicked out of Sparta and the Misthios will hunt him down. Archidamos is the wrong choice. The Misthios will be exiled from Sparta in this case.

7 The Kingfisher And The Robin: To Talk or To Kill

Agapios, sweet as he is, needs the Misthios' help. His town has been ravaged by a group of bandits. After conducting an investigation, it is discovered that the leader of the bandits is Neritos, Agapios' brother. Agapios believes his brother can change for the better and pleads for his brother's life. It's a choice between the power of change and the corruption of evil.

There are not major consequences for this choice, but it does have an immediate impact. If you let Agapio try to talk to his brother, then Neritos will kill him. If you kill Neritos, Agapio will be saved. It's difficult to kill someone in front of his loving brother but, in this instance, it's the right choice.

6 Portion Control: Spare or Kill Suspicious Civilian

There is blood splattered across the ground and a Spartan angrily pacing around it. He sends the Misthios to hunt down the Athenians responsible. The only problem is that Athenians didn't do this, a group of civilians did. It looks as though a group of starving civilians committed a major crime by killing Spartans and stealing their cargo.

The player has to decide if they want to enact justice by killing them or let them escape with some of the stolen food. In the violent approach, you have to kill the civilians and the quest will be over. If they live, you find out a mercenary actually killed the Spartans and you are tasked with killing said mercenary.

5 The Wolf Of Sparta: Kill Or Spare Nikolaos

Assassin's Creed® Odyssey_20180923223628

This is the first major story decision in the game. Nikolaos, the protagonist's father, threw them off a mountain. Now his child has returned. He/she can take revenge by killing him, or spare his life. Nikolaos caused some major suffering in the protagonist's life, so killing him might be tempting, but it will impact the main quest greatly.

Killing Nikolaos will result in the death of Stentor, the protagonist's brother, as well. This will block off a whole series of quests later on and make it impossible to receive a happy ending. Sparing Nikolaos' life will allow him to come back later on and make the happy ending possible.

4 Blood Fever: Spare a Family Or Spread A Disease

Kephallonia is a beautiful island, and it serves as the home for our favorite mercenary. A destroyed village sits on the island like a scar. The air is grey and it looks like a ghost town except for one tied up family. This family has a deadly disease that can spread easily. Kill them or let them live?

Letting the sweet family die will stop the disease. Their deaths will save countless others. Letting them live will have dire consequences later on. Towns will fall victim to the disease and Kephallonia's citizens will suffer. This is one side quest that has a major impact on the world of Assassin's Creed Odyssey. 

3 The Last Cultist: Kill Or Spare Aspasia

Players will spend a lot of time hunting down cultists across the Greek world. They are hidden all across the map in busy cities, isolated islands, and sailing across the seas. After you finally kill all the cultists, the leader will reveal herself. Aspasia is a character that helps the Misthios early in the main quest, but she is actually evil.

This optional end game decision tasks players with killing, sparing, or kissing her. The decision will not impact the game at large, but will change your understanding of the Assassin's Creed universe. If you decide to spare or kiss her, then she will live and form the Templar Order. If you kill her, then the Cult of Kosmos will simply be eradicated.

2 Ashes To Ashes: Save a Baby Or Kill A Baby Killer

The cultist, Chrysis, tries to stop you from chasing her by leaving a baby inside of a burning structure. You have to decide between chasing her down or saving the baby. It's a rather difficult choice because Chrysis will continue killing, but you can't simply let a baby burn.

Continuing the chase will cause the baby to die, and saving the baby will let Chrysis escape. The good thing is that a later quest will allow you to assassinate Chrysis. It's a difficult decision in the moment, but there is clearly a right answer.

1 Main Questline: Befriend Or Kill Your Evil Brother/Sister

The main quest revolves around the relationship between the protagonist and Deimos. Deimos is the protagonist's brother or sister, depending on what character you choose. They are also a member of the Cult of Kosmos. There are several dialogue choices throughout the game that revolve around reasoning with Deimos or hating Deimos. This is difficult because Deimos has done some terrible things, but they are still family.

If you convince Deimos that the cult is using them, then they will eventually turn a new leaf. If not, the player will have to kill them. It all results in either a jubilant family dinner or a lonely dinner for one.
