Endless Space is my all time favorite 4X game (sorry Endless Legend) out there beating the Civilization series and the Sins Of a Solar Empire in my personal list of 4X games.
I have played and replayed the game countless times to achieve different kind of victory with different factions. What makes it interesting as well was that games like Dungeon of the Endless and Endless Legend, they are all tied up in the same universe.
Looking at the trailer, the ship that sailed out of the planet looked particularly similar to the one in Endless Legend and I also think that they just left Planet Auriga. That is where you come in and continue after that. I’m just speculating but who knows.
I love the Endless universe and I cannot wait for this one to be out next year. Check out their official website to get dusted.
