For whatever reason, I felt compelled to reply to this, but anywho..
Your idea of "Average" stats is a bit skewed. In RPGs that use the D&D attribute system of 3 to 18, an attribute of "15" is not average.
This is essentially how attributes were explained in the D&D Manual:
• 3 is a crippled individual, or someone nearly deficit in whichever attribute. (e.g.: 3 Agility/Dexterity means you can't even walk.)
• 8 is slightly below par, such as a computer nerd who has below-average strength, but isn't completely weak.
• 10 is the average, every-man regular joe attribute level. e.g. 10 intellegence is equivalent to an average person's IQ
• 15 is very, very high. e.g.: 15 to 17 strength/might would be the equivalent to a professional bodybuilder
• 18 or higher is the attribute level of a demigod, for lack of a better word. Example: Hercules may have 19 strength in a CRPG
