Right after you hit “New Game” you will be asked to select your crew. What you really want is one crew with 3 skill in Engineering (orange) and a different crew with 3 skill in Intelligence (blue). You will always want a good engineer on hand to build and maintain your craft and you will need at least one strong scientist to man the research console. Beyond that, Speed (green) is always helpful, mostly for engineers and it’s good for the other 2 crew to have decent skill in either engineering or science.
