I bought it a while ago when it first came out.
Fun game. It's a really interesting space sim. Lots of freedom, lets you build complexes, manage fleets, etc.
The only problem is it had a few really annoying limitations that really ruined it for me.
1. Bad AI. Having a fighter wing escort you usually meant they would fly into stations you were docking with, crash into gates, fly into enemy ships, or even fly directly into you while "defending" you in a dogfight against enemy ships.
2. Shallow economy. It looks deeper than it is. Ships moving cargo, stations producing things from a complex series of raw materials, supply and demand, etc. It's all an illusion. Things are in actuality just poofed into existance when needed and removed when not needed. You can make a station in the ass end of nowhere producing more goods than the entire universe could consume but traders will happily pop into existance and buy it up endlessly. Some of it might trickle into trade depots, it might even make its way to a few factories - but even if you produce 100,000,000,000 of something you can still sell *all* of it as long as you price it affordably, and the factories on the other end of the universe will probably never actually get any of it since it will be destroyed or just removed somewhere along the way. I found this out while doing that horrendous hub quest. I had to manufacture an obscene amount of crystals and microchips and crap and then when I was done I had huge self supporting mega complexes churning the stuff out faster than every factory in the universe could possibly use it - but it was still being bought regularly and just making me endless credits, and the factories on the other end of the universe still never had any of the stuff in stock.
Don't get me wrong, it's a lot of fun. If it wasn't for #1 above I would play it just for the combat. Maybe one of these days someone will come up with a patch or mod that makes the ships smart enough to not crash into you while protecting you - if that happens I might go back to it. Small scale combat is still fun enough, it just has so much potential for great fleet battles if the flight AI wasn't so lousy.
As-is it's still kinda fun to fly between large enemy capital ships with a small fast fighter and just have them blow eachother up since they're dumb enough to fire their big anti-capship guns at you even though you're flying right between them and the shots will inevitably miss you and hit eachother. It's just kinda disappointing when your own capital ships do this just because they decided to fire at that little khaak fighter who flew by instead of the gigantic khaak destroyer bearing down on them with heavy beams.
