7. Full Trading between allies as far as technology and planets and ships .
Not really doable -- TEC and Advent are the same species, but Vasaari and the others aren't ever
close to related.
4. Nice looking structures for planets or at least with upgrading the population it looks better then a bunch of ants crawling on the planet 24/7 days a week.
People
are ants, when viewed from orbit

Fact is, those things you see in orbit need to be
reduced in size, majorly. As it stands they're the size of small cities

3) Managing my empire in the middle and late part of the games took so much time that I rarely watched the battles. Over 95% of my time was spent zoomed out clicking and placing icons. Here, Homeworld had a far superior feel. In that game, I watched and participated in almost every battle. With Sins, I sent in my fleets and returned to managing, checking occasionally on the progress of the battle by clicking the system and looking at the colored unit bars. What's the point of creating good graphics if there's little time to enjoy the fight?
Wait, you
complaining about the tactical UI they're working on? I know that its not up to snuff (yet) but personally I like it quite a bit!
And I'm not sure about what you mean by not having time to manage fights -- you should have plenty of time "free" to manage fights if you really want to.
4) Please put most of the game controls on screen and mouse-clickable. In Starcraft and Age of Empires, I rarely had to go to my keyboard. Unlike a turned-based game like GalCiv II or the Civilization games, where I have plenty of time to play with keyboard shortcuts, in an RTS, I don't want to have to hunt my keyboard. Everything I need should be clickable on-screen.
Just use yoru left hand on the keyboard -- thats all you really need. qwert and asdf are used as "constant" hotkeys, no hunting necessary. Also places your hand in good position to use the "shift" and number keys as needed, as well as zxcv if you want those zoom controls. That said... how do you
avoid using the keyboard in starcraft?!
5) Please don't try to make this RTS GalCiv II (I'm hoping GalCiv III will accomplish that).
I'm hoping that was a very not-funny joke.
I think a better model is the Total War franchise which uses a turn-based strategy map for managing and RTS for combat. It's a balance that brings together the best of both worlds. True 3D like Homeworld would also be a lot of fun.
This game is what it is -- play imperium galactica II for a similar game (I've heard nexus floating around as another similar). As far as 3D goes, its already in game, its just that the Z axis doesn't get used much. You have to use the "move"
button (no right clicking) and the tilde (~) key for it. (On american keyboards, ~ is the the left of the number row. On other keyboards, ~ is elsewhere but the key needed is still the one to the left of the number row).
