I play it. Wasted HUGE amounts of time just to lose whole fleets to mistakes with logistics. So much so fun (I refer to it as "Mount & Blade in space") - But it still lacks content, even after the update.
The time between updates was superlong, was beginning to regret backing it. There still aren't really features to influence the galactic politics and powerdistribution - but it is getting there. If they get it all done (Also there are REALLY good Mods where they could steal ideas and code *g*) it would be an AMAZING game.
So far: If you don't have it, back it.
