In Space Opera, players must choose the type of personality they wish to portray as player characters (abbreviated hereafter as PC). Depending on that initial choice, the PC's personal characteristics, skills, and career options will be optimized to suit appropriate fields of endeavor for his character class. In other words, if a player desires to operate a fighting man or Armsman, certain of his personal characteristics will tend to be weighted toward those abilities and skills he will need to be a success in his field, Of course, there will always be a slight trade-off, and the PC may have less of an advantage in other fields and skills not associated with his class.
