This is probably an obvious question, so I'm appending it to this thread instead of starting a new one:
When choosing skills, are you restricted to putting points only into those advanced skills listed in your character (sub)concept? I assume Yes, but can't see it written anywhere. Possibly I'm just being blind.
Otherwise, why wouldn't you tend to put points into advanced skills much more than basic, since if you don't you can't use those skills at all...
I'm sure this will probably play out just fine in practice, but I can imagine a player trying to 'game the system' by putting one point into every advanced skill (regardless of whether this would actually be a good idea or not). Is there anything to stop such a player doing that?
