For the first time in the Assassin's Creed series, you can pick whether you want to play the entire game as the male protagonist, Alexios, or the female protagonist, Kassandra. Alexios and Kassandra are siblings living in Ancient Greece -- they used to be spartans, but now they live out their lives as mercenaries, taking down mysterious plots or just killing whoever's necessary for the money. Through dialog choices, you get to choose their personalities: whether they're funny and sarcastic or more serious and to-the-point. While the main story mostly plays out the same no matter which sibling you go with, certain scenes read differently depending on whose point of view you experience them from, so you might want to play through the game a second time to see the changes for yourself.

The combat in Assassin's Creed Odyssey is really up-close-and-personal. Wielding weapons and shields, your skill with blocking and parrying is as important, if not more, than landing strong blows. Enemies are relentless and aggressive in how fast they attack; parrying them is especially satisfying because of how tough they are. Chaining your defensive moves into attacks that take your opponent off-guard is great, rewarding you with some awesome finishing animations. Taking your time to read your enemies before going after their weaknesses pays off in the end.

You get to navigate out in the open waters to get from place to place, getting hands-on with the full mechanics of steering your ship while firing off cannons at surrounding enemies. Using the directional indicators to line up the perfect shot is incredibly satisfying as you take down one ship after another, sending them sinking in flames. There's a full crew aboard with you, helping to give plenty of liveliness to your surroundings as they shout in anger and cheer in victory as you go along, with dynamic weather like raging storms that adds to the realism and intensity. It's a lot of fun and serves as a nice way to break things up from normal missions on-foot.

The in-game map is absolutely gigantic. There are so many places to go and so much to do in the world, easily giving you over 70 hours of content. Exploring the rolling hills and ancient cities of Greece and the nearby Mediterranean Sea is such a joy because of how lush and beautiful everything is. Wandering around often surprises you with new side quests to find off the beaten path, with new characters to meet and history to learn about in whichever area you find yourself in. And there's just a ton of other mythological secrets and fun diversions to discover as you adventure throughout the world.

There are some well-done instances where your decisions have real consequences with the side quests. Depending on how you interact with side characters, if you're polite to them, or if you choose to be mean and uncaring, this will change how they view you. If you cross the wrong people, it could have dire effects on certain locations, and some of the characters can outright die if things end up spiraling out of control. It's up to you to find out how everything plays out depending on how you role-play as Alexios or Kassandra.
