The only things missing are the four big expansions: Poseidon, Hera, Hephaestus, and Rise of the Titans. Hopefully those will be on their way soon.
I should say that the team behind the Kickstarter deserve huge kudos: Despite the obscene amounts of stretch goals and add-ons, they have managed to deliver every before time (well, almost everything, but let's see what happens with the rest - the originally announced delivery date was stated to be December 2017).
Unpacking the Big Box
The Add-Ons
Extension Kit Add-on
Just some extra objective markers and cards
The Manticore
3D Terrain Set
Corinthia
This doubles as an expansion for the Conan board game. The winged gorilla (or Herald of Typhon) appears in the Conan story "Queen of the Black Coast"
Atlas
Ketos
This monster figurine is originally from the Conan board game, but apparently it fit for some Greek sea monster too, I guess!
Echidna's Children
The Basilisk, the Chimera, and the Teumessian Fox
Heroes of the Trojan Wars
Agamemnon, Diomedes (my favourite Greek hero in the Iliad), Penthesilea (yeah... her armour is... yeah), Ajax (but which one, Monolith, which one?! I'm guessing Telamonian Ajax), and Paris.
Oedipus and the Sphinx
Judges of the Underworld
I don't understand the design choice behind these figurines. I like them on their own, but I never imagined Mions as an undead Oven Man...
Paolo Parente's Guest Box
I think it speaks for itself.
An extra game board
On one side is a board for sea battles, on the other is a board for Thermopylae.
Add-on Books
The Roleplaying Game
Art Book
I love how the picture on the second picture is recreated with the miniatures in the next book.
Compendium
This contains scenarios, and maybe more. I haven't looked much at the contents yet.
Stretch Goals
This box contains all the stretch goal miniatures and a few other goodies.
A little pile of cards. Everything is in both English and French, so almost half the cards can be discarded (hah) or put away in the cellar.
