I bought it, it seems to be a slightly shinier Sins of a Solar Empire, with a different battle system.
Instead of the real time battles of Sins, you get a turn based cinematic style based on four stages. Arrival/Long Range/Medium Range/Short Range. You choose a "card" which contains a special ability for each segment, played against the choice of the opponent. Right now the AI seems to cheat, as it always chooses the ability which counters your choice.
If you liked Sins, you'll probably like the game. Its technically still in beta, but its already very polished.
