I was a huge fan of Master of Orion, hope we will find the good elements of this old game in this promising new one 
1) It seems that we're going to treat each planet as a province, if I'm interpreting the screenshot right. We've been told that the maximum number of stars that can be generated is 1,000, and that none of them will be planet-less systems. We don't know the cap on planets per system.1. It is written "Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space."
So, the question is twofold. First, just how much interstellar real-estate are we talking here? A single galaxy, of which there are billions in the universe, can be thousands of light-years across. Traditional space strategy games don't operate on this kind of scale. Second, what level of representation are we talking about here? Planets? Star Systems? Space Counties containing dozens or hundreds of stars? For reference, our Galaxy (which is big, but not unusually so) contains around 200-400 billion stars.
So my expectation is that we'll be fighting over star systems in a constrained little chunk of space rather than fighting over the whole galaxy, but there's a lot more room out there and if you try for truly galactic strategy, it can get unmanageable fast.
2. So, something like Gratuitous Space Battles? I could be down with that.
3. EUIV technically has characters too. They just matter a lot less.
Has there been anything about terraforming worlds?
I mean something like turn barren rocks into livable worlds and then put deadly life on those worlds so the colonists there will become perfect soldiers from surviving in hostile environments. Need to keep my armies sharp somehow.“Nuke the entire site from orbit--it’s the only way to be sure”
Nobody knows yet; though in the leak it said something like 16th of February 2016 so perhaps then.When.is the release date?
