If Mobius is still having troubles with the error message... I had the same thing, but once I enabled jpg/tga textures it worked like a charm.
Now the feedback. I liked it a lot. I especially liked the lack of shields. And weapons with limited ammo. And the the lack of shields. I also liked the finite afterburner reserves, because IMO infinite afterburners are as much a cheat as shields. And I also liked the lack of shields, which made combat interesting.
Also the no targetting thing was interesting. At first it was a bit annoying when I had trouble figuring out where to go and where to dock. And hostiles kinda flew in my face when there wasn't a distance indicator on them. But when I got used to it, I liked it. It actually improved my situational awareness as I had to keep an eye on my bearings and where everyone was, because I didn't have targetting computers to do it for me. That was a ballsy move, my hat's off for you...
After getting the sensors it was like OMG! HAXX!!! Killing poor pirates at max range... It was a kind of a bummer. Made combat easier.
There wasn't a lot of chance to take on capital ships. But during the bridge shooting, I don't think the cruiser shot at me at all... I haven't really tested the capships abilities yet thought. Just talking about campaign experiences here. I did like the noise the cap ships made when shooting. But it could use some more work. Like a real loud BOOOM BOOOM BOOOM so everyone knows big guns are singing. To really distinguish them from the peashooters on fighters... I'd like capships to be credible threats. Like they were in FS1 before getting shields.
Overall... Really great work.
