The Olympus Edition is an all inclusive version of Omen with different card backs than any previous version of Omen. It has the same number of units, but much fewer cards. It is an exclusively 2 player game; there are no extra cards or coins to accommodate 4 players. Deckbuilding/Drafting is handled differently than in the 2nd edition.
The Olympus Edition contains 1 of every Unit ever published for Omen. Some units have been altered to make them work within the constructs of the new format. However, this is considered to be a "catch all" release for people who have wanted Omen but have missed out. Relics are not present in this edition as they were exclusively a Kickstarter expansion. If you already own Omen, there is no reason to purchase this version of Omen.
