Trade and appraisal
Combat (melee - maybe heavy and light separate?, missile, thrown, unarmed) – not sure if I want to include this aspect from SWN. But I thought I'd at least consider it.
Armor (heavy, light, unarmored) these wouldd probably give some sort of bonus for skill (not necessarily AC)
Culture adventurer/criminal/region/race, culture adventurer might include: how to get along in a variety of cultures, and basic adventuring skills: lighting fires, riding a horse (out of combat), appraising common goods, recognizing common monsters.
History (probably not available to most PCs)
Profession (whatever trade you can think of!)
Religion (probably not available to most PCs)
Science & mathematics
Tech (primitive, arcane) – contemporary technology would be covered under other skills or the relevant profession
Sailing and boating
Sleight of hand
