I might be repeating some things others have said, I only read half the posts, but:
1) I think the yor economy is fine and like how different they are. Their buildings are fine too. I'm not requesting that they not be changed. I'm just saying, when 'fixing' races due to complaints, fix things that aren't operating as intended, add whatever ya feel like, change 'em up in whatever ways ya feel like, but I request those doing so just keep in the back of their mind the need to avoid taking away their uniqueness while doing so. Races should have weaknesses as well as strengths. Don't fall prey to constantly overbalancing like WoW until everything is the same as everything else. The game just came out, so obviously it isn't much of an issue yet, I'm talking long term. It would be all too easy, one little step at a time, to accidentally end up like this w/out noticing, so better to mention it early.
2) The rally point map that comes up doesn't seem to actually show rally points, or if it does they are so small I can't see 'em. The trade route map, on immense at least, is too small to gain more than a very general idea where the routes are.
3) Maybe this already exists, but I'd like an ability bind a key to turn on all travel lines for all ships so I can more easily tell which ship I'm sending where at a glance in congested areas. Then, I could turn it right back off again once I've gained the info I need, and could do so w/out having to go to an options screen. Could also use it to trace back and figure out 'which ship is it that has this destination point I see here?'. Some times I load a saved game and see a lone destination point in a weird place and wonder why the heck I sent anything there? Which of my many many many ships out there is the one I sent here and why? hehe. Or another alternative, the ability to click the destination points, make them selectable, and upon doing so, the travel lines for that destination show up. Same w/rally points. Would make things less confusing when loading up an old save game from an immense map when trying to remember what the heck I was thinking.
4) This might be intended, so just ignore me if so. When cultural victory is enabled, the victory screen tells you how close you are to a cultural victory. If you are at war, you can't have a cultural victory. This is fine. But if you are at war, it no longer tells you your percentage towards completing a victory. On an immense map when you're past the point that its certain you are gonna win and you're just wrapping up, it'd help make for a quicker 'lets finish this' option if I could see that I'm already past the cultural victory point so if I could just make peace I'd instantly win. There's no gaurantee I'd be able to make peace after all, so that'd still be up to me, the player, but the information will let me know there's a quicker way to have my victory so I can start up a new game. => And its not like this info is exactly hidden from the player anyways, the minimap gives you a general idea of your cultural percentage, but since victory needs a specific number it'd be nice to be able to see where you are at, even if you happen to currently be at war.
5) This is one that probably is as intended, so ignore as needed. But when I get close w/another race adn want an alliance, but can't because they don't have the tech (even though I do), it seems somehow wrong. I turn tech trading off, so I can't give them the tech either. I don't want to be able to give them techs, mind you, but in this one instance it creates a problem. Perhaps, as long as I have the tech, and in games w/tech trading off, I should be allowed to propose it if I meet the other requirements (close enough relation, pay whatever it is they demand, etc..). In other words, only the proposing party would need the tech. This would only be needed in games w/tech trading turned off. Makes diplomatic victories a bit difficult as it is in no-tech-trading games when the AI just never researches the tech. Or, as an alternative, it could be an option in the trading screen to tell someone you're close enough to that you'd like them to research a specific tech next on their list, if you're willing to pay them enough to make them do so (make it very expensive). This way you could guide them to getting the alliance tech for themselves if they don't already have it and you're not willing to wait.
