Things which will be crucial to you here are going to be extending 
modules and classes, as well as inheritance.

class Race
  MAX_SKILL_LEVEL = 10
end

class Elf < Race
  MAX_SKILL_LEVEL += 1
end

Race::MAX # => 10
Elf::MAX  # => 11

And you can also specify unique skill levels (for instance, your 
Swordmanship max skill may be 22 because of a unique sword you have, it 
doesn't raise EVERY skill max...)

Does that help a little?
