What do you guys think that the difference between a static core and a dynamic core are? At first I thought that "dynamic" is for a ship or something that would move like dynamic location (although now I think about it, it sounds like a really strange way of putting it), but then some of the comments made by JC wouldn't make sense for example when he talks about making the station move in the gameplay video he says it would just be a matter of putting engines on (although I could be remembering wrong, probably go watch that again after I post this), and when he talks about constructs not being anything until you build them out in other interviews (XPGamers, I think,again memory :\ ). So I believe that you can toggle between the two states to make a zone editable or not. If you don't know what a core unit is the latest 3D artwork posted on the DU twitter and is was said to be the first block of any construct. And if this is me being dumb, let me know.
But then again the tweet reads "different types and sizes of core unit" So I am not sure again, why would you need different sizes, unless that is what controls total build area, but a selling point for this game is unlimited build space.
