I have a system devised for these things... Let me rustle up the papers.
Okay.. Primary aspiration is decided by the zodiac signs, which all fall into 4 elemental categories: Fire, Earth, Air, Water.
Aries, Leo, Sagittarius = Fire = Romance
Taurus, Virgo, Capricorn = Earth = Fortune
Gemini, Libra, Aquarius = Air = Knowledge
Cancer, Scorpio, Pisces = Water = Family
These are my four favorite aspirations so they take top priority. This system is pretty in sync with the stereotypical astrological personalities. You may note that all the zodiac signs within a category are rather different from each other in regards to in-game personality. This prevents getting stuck in a rut and having all your sims of a certain aspiration have pretty much the same exact personality according to your own personal stereotypes.
Secondary aspirations, on the other hand, are based on stereotypes. I took each aspiration, minus grilled cheese, and considered each personality trait, then decided half to be more of one thing, and the other half the opposite. This is what I got:
Pleasure: Sl, Ou, La, Pl, Ni
Family: Ne, Sh, Ac, Pl, Ni
Romance: Ne, Ou, La, Se, Gr
Knowledge: Ne, Sh, La, Se, Gr
Fortune: Sl, Sh, Ac, Se, Gr
Popularity: Sl, Ou, Ac, Pl, Ni
The one they conform to the best determines the secondary aspiration. If the secondary aspiration comes up as the same as the primary, the second-most conforming secondary wins. What this makes all of Strangetown.. I really couldn't tell you, but it's easy enough to find out.
