its very simple, a robot mission should be easier than a manned mission.... with no life support it is actually much harder and requires more planning to send a robot.
Kerbalism was my favourite because of the added radiation, part malfunctions, stress and things like nitrogen for pressure
Life support should all be optional but PLEASE include it. its almost silly to go for such realism with parts and engines without air, food, stress, water and part malfunctions/repairs
thank you very much, Love ksp 1 when i can get kerbalism to work properly (although it needs to be a base game function to work properly and with things like fast forward which screwed every LS mod i used)
