Assassin's Creed Odyssey
It looks like there is a lot of content coming for Assassin's Creed Odyssey after its release. This content includes two additional "Story Arc" releases and Assassin's Creed 3 Remastered? Uh, okay?

This post-release content includes both paid content in the form of the Season Pass along with free content updates.
Story Arc 1 - Legacy of the First Blade:Story Arc II - The Fate of Atlantis:

The paid Season Pass can be bought separately from the game but is also included in the Gold, Ultimate, Spartan, and Pantheon Editions of the game. Holy crap, there are a lot of editions of Assassin's Creed Odyssey.

Beyond the Season Pass, here are the free content packs that are coming.
The Lost Tales of Greece:Recurring In-Game Events:Discovery Tour:

Damn, that's a lot of content that's being planned. I suppose that's a good thing considering Ubisoft has already said there isn't going to be a new Assassin's Creed coming in 2019.

Assassin's Creed Odyssey is out on October 5 for the PlayStation 4, Xbox One, and PC. Those who get the Gold (or above) editions get to play on October 2.
