Page 36, in the description of the average human archetype I found this hidden gem:

Quote

Just remember, character creation is your only chance to spend XP on characteristics (otherwise, to increase a characteristic you need to purchase the Dedication talent; see page 81). We recommend you spend most of these XP on improving your characteristics, while saving at most 25–35 experience for talents and skills.

It's a great bit of advice, but in a really wonky spot!

I pretty much give all my players that advice anyways.

Definitely good advice, although in Star Wars, I try to put all my XP into characteristics at the start.
