So I finished the main story now in Assasins Creed: Odyssey.

It was a pretty huge anti-climax. After all that, the ending had nothing to do with the cult, no real final boss... it just felt like a super-dragged-out side mission, basically. Still, a pretty god side mission, even if Diemos/Alexios is a complete wanker and an awful "villain". Can't imagine what the game is like playing as him. If you do, is Kassandra the villain? I got a happy family ending which just didn't feel quite right, but still sort of was nice anyway in the end. I suppose they are all 4 complete assholes in the end, even Kassandra, so.

Then, after that, I proceeded with what felt like the "real" main story and killed off the rest of the cult.

Also anti-climatic. OK I was surprised by Aspasia (I was convinced it was the Oracle/Pythia), but then I managed to fuck up the dialogue options and just let her go, which I didn't want to do because she seemed to have some complete faschist ideas.
.
Apart from that, I've done most of what seems worth doing in the main game. I've killed/beat all of the Legendary animals, and all 3 mythical beasts - which were all the most fun three fighs in the game and the only real boss-fights, something I missed quite a lot in the main story otherwise. I have uncovered most of the world map and been to all islands as far as I can tell.
So, now I just started the "Gates of Atlantis" or what it's called, and it involves this Layla Hassan in modern times quite a bit. I don't really understand much, as this is the first Assassins Creed game I play and there seems to be this other, parallell story arch that goes across games but in modern times? Anyway, I read the expansion is really good, so gonna give it a try.
All in all the game has been amazing though, but it suffered a bit from monotony after a while. The landscapes are all the same, the forts are all the same, the enemies are all the same, etc.
