I've been playing for a few days now and everything works quite well actually. Stability has improved greatly for me since the last release, haven't had a single crash in more than 10 hours of play.
I really like what you've done with the mod, especially planetary exploration. It complements very well with the rest of the game I think, and is a viable alternative to piracy or trading for the new player. I've also tried the new UIN Prototype (I always play UIN) and it's really powerful. The only complaint I have is that it's actually a bit difficult to use it's main gun due to it's rotation speed. It turns so quick you have to zoom in a lot to get accurate shots of the particle cannon, which is already not the easiest gun to use due to the slow speed of the projectiles. Most of the time, I end up spraying an arc in front of me instead of hammering the same point because of the violence of the turns.
Personally, I'd rather have a lower turn speed and a universal mount instead of an energy one for the main gun. UIN large energy guns area mainly short ranged, and being able to mount a railgun on the ship would enable it to play in a support role better. Or those really really neat dual 60pdr guns
Anyways, great mod as always, really enjoying it so far !
