After playing through the game a bit, I can think of only one complaint that I have:

Since there is a lot of management (macro and micro) going on, I find it that when you send your ships in to take a planet, or are taking over several planets at once, it is hard to focus in on that battle and appreciate the little details that the developers went into in coding and making the game look as beautiful as it does on its highest resolution and settings.  I find that when taking other planets, I am still forced to look at my other planets and see what is being built and am unable to look at the battle taking place because so much needs to be managed at once in order to stay on top of things. 

Does anyone else feel this way?  Or am I just crazy?  

Anyway, that's my minor complaint.  Still a beautiful game though.
