Thank you all for answers! I appreciate it, getting better every single day playing this game.
I restarted Aurora and already everything is working better. I played a lot with the civilian / military designs, I have better idea about the minerals and their production etc. Experience makes wise decisions as it seems!
I will soon have my first ship designs ready so that I can post them in the shipdesign forum. In the meantime though a question - sometimes building a new ship may be cheaper than refitting the old one, correct? How can I easily figure this out without having to actually move my ship back home and doing this?
The model I am facing now:
Lilian class geosurvey ship
set for 24 month missions
has 1 geosurvey sensor
has 1 Hasswell Mk I. commercial conventional engine (25 HS)
has 2 fuel tanks
Lilian refit I class geosurvey ship would have:
set for 24 month missions
has 1 geosurvey sensor
has 1 active sensor
has 1 Barracuda Mk I. nuclear engine (25 HS) / might be two depending on the performance x size
has 4 fuel tanks
Has 1 gravitational sensor (= is no longer civilian ship)
has 1 jump engine (to be designed).
+ necessary engineering spaces (probably like 10 or more of them, depending on %)
Is it viable to start from scratch or refit?
