EmperorPardoxant: I'll make a test of those ranges in the official release, but in beta 4 I wasn't able to change enough settings to make it functional. One of the issues is that ships either have to have incredibly high deceleration compared to acceleration or you have to wait an extended period of time for them to cross those gravity wells, the game engine basically decelerates ships by calculating the distance remaining, so the end of a trip is rather slow as it decelerates unless it is a really high value.
The other issue was I couldn't change all of the icon ranges and other options at that zoom level for some reason, maybe I couldn't find them. I'm not opposed to it, but I was having some issues with it, also there are some funny problems with weapon projectile speeds (basically would need to be on the order of 1000 km/s to make much sense with those ranges and that looked really odd) and you would never see ships in battle. Strategically it is fine, but once you zoom in, you are looking at icons shooting icons.
if someone captures KDY, then the option of the research could be considered stealing the designs

We'll have to see about strike craft. There may be interesting ways to hack in strike craft with hyperdrives (basically a carrier with no visible mesh that spawns fighters once, dunno)
as for ship cost vs numbers. I think I will make larger vessels be expensive enough that you want to retreat rather than lose them. The build time could be one cost (strike craft and small vessels could be assembled in days or less with advanced production facilities so I'd like to make a large destroyer roughly 10x -20x the production time) Additionally the resources could be rearranged making larger vessels need more of the exotic resources than the simple ships. Also keeping with in universe scenarios it would be best to keep your large ships guarding key worlds and only drawing them off when necessary and only for short periods of time.
I'd also like to see the option for refueling vessels from your resource pool, with hyperjumps and combat depleting the anti matter resource, but we'll see about that as well (I'm going to go rustle up some devs on this very issue)
for the music I highly suggest popping in your favorite SW tracks on a playlist in a player like winamp and leave it in the background.
