I just saw this game on steam's pre-order special. It looks like it's a TBS meets RTS, meets Space Sim of sorts. Great presentation!
Here's a 30 minute quick look on youtube:
UPDATE: I bought it today, and have been playing the alpha.
It bares more of a resemblence to Civ than SoaSE. I've never played GalCiv, which could be similar. The combat is interesting, but most agree that it's too simple right now, but fans/devs are chatting on the forums regarding how to make it more complex but retaining the board/card-gamey quality behind it. The Alpha is only single player only, up to 8 players. The multiplayer will be launched in the coming month(s). I really enjoy it!
The game revolves around managing colonization vs militarization vs technology/science vs peace/war/trade negotiations, in a nut-shell.
It's a Turn-based strategy through and through, but the combat plays out like a card-battle game that I can't remember a reference too. No direct control.
