Ok, thread necromancy time.
I've recently picked this back up and gotten started. Have a lot of ideas, though my biggest challenges will be scripting events, my graphics, and loading/saving from XML files.

Anyway, current plan includes some of the following:
Girl Stats:
Physical: Strength, Agility, Stamina
Mental: Smarts, Wits, Willpower
Social: Charm, Beauty, Manners
Personality: Confidence, Obedience, Spirit
Those are the basic 12 stats. Other stats will not be displayed with those, but have their own indicators. These include:
Loyalty, Love, Health, Energy, Happiness, Fame, Experience, Level, Age.
Girl Skills:
Combat: Attack, Defense, Magic
Service: Healing, Maid, Advertising
Work: Barmaid, Waitress, Gambling
Sex: Normal Sex, Fetish Sex, Stripping (will probably wind up expanding this section a lot)
Girl Fields:
Name
Genre (sci fi? Magic girl? Fantasy?)
Hair
Mother, Father, Siblings
Traits are a work in progress. My intention is, rather than adjusting a girl's stats, traits will play into how she performs in jobs and how her stats are used. For example, a line of tiered 'Martial Artist' traits, that allows her to add a portion of her Attack skill to her Strength to determine damage in combat, when unarmed.
More details to come, and as always, open to suggestions.
