The art was definatly one of the better things about the game, shame ships kind of slide-sideways instead of facing the direction they're going, and how guns kind of sprout weapons fire in unlikely directions. None of which is your fault, since you just made the models. And I do like how the subsystem art reminds me a lot of Space Empires' subsystem art.
But isn't it fundamentally dishonest to release a game as "finished" and yet have the game be clearly unfinished. I really don't think "it is modable, so you can finish the game for us" is a good excuse. The game is so unfinished, and literally has no balance whatsoever, that you'd have to mod out the entire base gameplay and start from scratch simply having it as a graphics-engine for it to be any good.
I'm not just coming from nowhere on this, I did purchase this game, and gave it a good 6+ hours of gameplay before discarding the game.
If you really want a strategy game with the same theme, sword of the stars 2 is really your best bet. It isn't perfect, but it has lots of uniqueness which makes up for some of its worst flaws.
