Just a KSP player
My builds are straightforward, my piloting skills not great (so my craft tend to have delta v to spare)
I mainly play career mode.
I will try to put the tech level in the craft name prefix:
EK3 means can be built with tech level 3 components and is a good craft for career or science mode. EK4 would be tech level 4 components .. etc
EK without a number means - sandbox or engdame science or endgame career build
