This game is absolutely outstanding! Scenario wise, as MoratGurgeth mentioned, it's a closest call to HomeWorld 2's level I've ever seen. And that's a major plus. Mechanics are quite good, although I wouldn't mind having a chance to create groups of ships, which I could reselect by hitting a number key.
Thanks! Homeworld 2 is my favorite game of all times, and as you have probably guessed, the main inspiration behind this game.
