Brian and I both share the same philosophy when it comes to skills, less is more. Meta skills are a way of having less skills that enable your characters do more.
More is less
The more skills you have in your game the less capable the characters are. If there are only 40 skills and a character can afford to buy 10 plus some body development, weapons and perception then they have 25% of all the skill bases covered.
If you have 100 skills in your game and they can afford to buy 10 skills then the character has only 10% of all the bases covered.
