Hey. played this game for about 14 hours now.
Here's what i built so far. It's organically grown (kept changing & adding stuff according to what was needed/flaws.)
reactors in middle, sorrounded by armor, then some crew quarters and cargo. Nacelle like things have thrusters and manuevering thrusters, heavily armored because having them shot off constantly was a hassle.
