Tips? Aptitudes are not hard. There are a number of aptitude templates on p. 44. Most people should fall in those ranges. Someone who does not fit in those ranges are worth noting. Skills are not hard either. Write down a few things that describe the character. For example, a hacker should have good skills in infosec, interface, and programming. Something maybe in the range of 50 or 60. An experienced hacker should have skills in the range of 70 or even 80. An inexperienced hacker could have scores in the range of 40 or even less. Being a hacker should mean they probably have skills in persuade and deceive as well, to convince someone to hand over valuable information. They might be poor in physical skill. The idea is to pick broad stereotypes, to say a lot about a character. An athlete would be someone who is good in physical skills. An enforce would be someone who threatens people with violence in the criminal world. A medic is someone who knows medical skills to help people. Actually, the lists for background, career, and interests would work as good stereotypes. The fields you use during character creation. You don't need to tally up the skills, just know if they are poorly (40 or less), moderately (50-60), or highly (70-80) skilled as those stereotypes.
