On page 49, during Step Six of character creation, there is a table which lists the drawbacks you take as a result of age. The table seems to suggest you don't start with a drawback unless you're and Adult or older.
However, on page 88 it says that all characters start with one drawback, usually a flaw unless other narrator allows you to take a quality-like drawback.
I'm a bit confused how those two statements overlap, but I think it's supposed to be something like this:
All characters start with one flaw. If you're a young adult or younger, you take one flaw of your choosing. If you're an adult, you can take a drawback rather than a flaw. If you're middle aged, your flaw has to be one of Agility, Athletics or Endurance. If you're old, you get one drawback, and your flaw has to be in Agility, Athletics etc.
Is that right?
I also thought that page 88 might just be in need of errata, since it seems strange that table 3-11 doesn't include the flaw for the young characters.
The sample archetypes don't really help, either. The older characters seem to fit my interpretation, but the young adults go both ways. The Heir doesn't have a flaw at all, while the Noble does (in animal handling).
