Best way to explain it is that the "base" game was completed as of 1.40, and that now he is focusing on "expansions" (the first of which was Adventures in Krell Space, released in 1.50). The 2.00 update was a game engine update that allows for saved games to be re-used as additional expansions are added.I was confused by the completed tag. Any idea on how much more content there will be or what update will be the last?
Other material (including a long-overdue update focusing on Khelara,the eventual addition of a Chambermaid for the Princess, the completion of Moira's storyline, and possibly a "Harem" event at the base) has been mentioned as coming out in future updates, with the expectation being he'll wrap those things up by 2.10. More may be added after that (the Dev admits there's a lot, still, to explore in the universe he built, here), or possibly he could start a whole second game (which he mentioned as a possibility when I asked about visiting the home systems of the Nilurians and/or the Syrax).
