Sounds excelent!
I especially like the new tech tree loving, the same old GC2/DA tech tree is one of the reason I stopped playing this game months ago. After tens of games the same old generic tech tree just feels too boring. I hope there will be even more stuff to differiant the Races from each other, just a simple UI changes and even more varied AI responses should do the trick.
Still I won´t be pre-ordering this one like I did with DA, because before the first couple patches DA was just too buggy for my taste. I will see how the user based reviews go and with most certainty will order this one after release, if not for anything else, just to support SD
ps. About the constructor I really hope its not just some governor screen tweak, IMO they should be as automated as miners. I doubt it will happen but the hope lives. Also the way Star Bases are handled could use some adjusting IMO, just way too easy to spam them all over the place. Maybe just restrict the number of SB even more.
ps x 2. And for the love of god, do something about some of the horrible UI screens that have been forgotten, like the rally point selection window and diplomacy screen. If nothing else, just add a button like "what could make this trade work" button ala Civ4. Iam tired of guessing what the AI wants from me and how much he values for example specific techs. Even better add trade values for techs/threaties/ships and so on, that way it would be easy to calculate deals. Also being able to trade older techs for AI (he has laser 5 why would he want laser 4) should be ditched, would make trading easier IMO too.
ps x 3. Kill the current espionage system. Personal opinion only ofcourse, but this was the most worthless and over "hyped" feature of DA. A more general approach towards espionage would work much better in a game like this. And pls pls pls do something about the groud combat. Where are my soldier/legions units that were mentioned during DA development
edit:
Ok I read the Gamspots interview and it seems that diplomacy and espionage will get some tweaking. I hope with espionage its a whole overhaul. But it seems this expansion pack will be more about content than gameplay changes, a bit letdown for me. Still great that SD will bring some of the expansions new stuff to GC2/DA in form of v2.0 patch.
