After upgrading to 1.05.071, the game is running very stable and smoothly. (Even on a system below minimal requirements: http://www.galciv.com/forum.asp?BID=GF&id=71726#72231) Some small UI improvements (planet's list autorefreshs when changing sliders) make the gameplay much more comfortable.
Minor races are, in my opinion, to weak. Especially their willingness to pay you 100+ for a year or longer when you offer them a handfull of nice techs, and being willing to make the same kind of deal some months later again after you researched new techs, makes it often possible to run an economy that is completly based upon the cash of minor races. That makes the game a lot easier, sometime to easy.
In spite of that, the game is very balanced, couldn't be much better.

Trading with the major AIs on higher levels can be very hard, but not to hard to be impossible - just the right kind of hard.
I sometimes got the impression that something is screwed about the random events (same bonus for neutral and evil choice?!) but it hasn't happend often enough to be sure that it is a bug, maybe it was just a strange coincidence.
The AI has become very good in the meantime. There are still things where it makes mistakes (and there allways will), but the important thing is: It's getting more and more clever with every patch.
However, I thing that the Yor are to weak, compared with the other AIs. In my games (usually playing on 'crippling'=all set to Genius), the Yor are nearly allmost the first to go. When upgrading the AI in the future, focusing on the Yor so they can keep up with the others would probably be a good idea.
Another thing I like about the newer version (1.04&1.05) is that now all kinds of ships play a role. In the earlier versions for example, I seldom used BattleCruisers and rarley met a BattleHammer, now these types can be encountered often and make more sense. I think the different shiptypes are well balanced now.
So far, keep up the fantastic work
