Hey man!
No need for double post. Also- welcome to the community.
first of all- this has been already covered- we have numerous posts, streams- you name it- you can dig answers yourself, but in short:
Gal civ 3 is not Gal civ 2, sure they both come from same lore but gal civ 3 is a sequel to gal civ 2, totally different game- let go the past- let go the bias.
Now to your questions:
* Gal civ 3 is a huge sandbox game- how you play it is entirely up to you. You can change victory conditions on fly. You can set up or dl maps how you want them.
* Planetary micromanagement was hell, though if you want it back- there is a special building you build and you can manually micro each planet to your hearts content. Hell- make a custom race with manually controlling over planets and you got yourself a months game here.
* You can rename them, just they are on a separate file. Cant do it ingame(might change in future). You might even find my planet name somewhere there, there was a special promo for naming stars.
* About spending- you have option to micro it- its just different than in gal civ 2.
* Have you noticed government tools? You can adjust spending for ships, buildings etc.
* This was a design chocie. Lots of talk in alpha stage- we the founders and the Stardock team made this decision. So for the better or worse it worked for the greater good. Improvements have bonuses, adjacencies and you can do lots of cool stuff with it. Its better than in gal civ 2, not perfect, but better.
* Syipyards also was a joint decision in Alpha between Founders and team- actually Founders made the idea in first place- so- blame us. For all intent you can do lots of cool stuff with shipyards(did you know they can move?)
* These features wont return as you have to remember gal civ 3 =/ gal civ 2. Seriously- let go the past. And modifications are being made constantly. Gal civ 3 is not fully finished- lots of cool stuff in future- for example- spying, comanders, expansion and so on and forth.
All in all- before you post- do some homework. The Gal civ 3 you are playing now is the joint ddecision of trial and error of Founders and Stardock design team. Most changes are for the better and greater good. To me you are saying there is no micro- well there is plenty of micro- the tools are there- just do your homework. Its diffrent but gal civ 3 expands on that what gal civ 2 couldn't do possibly. And its still being evolved.
