Lets light this a bit. Actual basic attributes ( subject to change ) are:
Fitness -> All that make someone good for physical tasks, strength and dexterity included.
Crafting -> Name it manual skill. All that makes someone good for manual tasks, good artisans or artists
Intelligence -> Self explanatory, this character is curious and learn fast. Involves cunning.
Charisma -> How good the character is for social interaction, politics and leadership.
Will -> How much the characters like to follow his own rules or pushing his own limits, also involves courage
Attributes are inheritable from parents and/or trainable and serve as modifiers for actions and decisions.
Its also planned to add specific traits over this attributes to better define some characters, but we are not sure if this can be added before first release.
Now, keeping in mind that we need the base attribute number as low as possible while being capable of defining interesting and useful characters for the game, do you miss something?
