Sins of a Solar Empire is real time space strategy game from Ironclad Games and published by Stardock Entertainment. Here is a short grab from the blurb on the Ironclad site,
"Sins of a Solar Empire is an innovative real-time strategy game featuring seamless transition between epic strategy and tactical combat modes, initiating what is already becoming known as the RT4X sub-genre."Beta 2 is available for pre-order until July 31st at the moment (needless to say I had to pre-order it :) ) and I must say it looks very promising. The visuals are stunning and the music is appropriately grand. To top it off game play at this early stage is very enjoyable with a wealth of strategies to devise. Strange how you don't often see those two together often.
The forum is pretty active with a lot of people making some excellent suggestions for improvements. There are also plenty of posts from the developers so it's not as if you're talking to a brick wall.
If this genre grabs you the same way it does me then I urge you to head over to the website and check it out.
