I don't want a superficial attractiveness system. I don't want it to be all about physical beauty. Attraction to superficial appearances should be in the system for creating certain types of characters, but so should attraction to intellectual, artistic, humanitarian, social qualities. A lot of people are attracted to a sense of humor. Some people may find creativity attractive, or intellectual pursuits. I'm attracted to people who enjoy nature. Others may find someone who is compassionate or empathetic attractive, I know I do. Common interests, say liking the same genre of movies or music. More things like that should be included instead of lots of physical attributes. The physical attributes should focus on things like eye color, hair color, as @DaWaterRat mentioned, not things like thin and fat. Yes, being attracted to bigger bodies is very positive and shouldn't be discouraged, but don't make thin and fat the be-all-end-all of attraction.
But I want to take it a step further and have primary and secondary points of attraction. Set the system up so we can say this particular turn on is more important and stronger than another. Don't limit it to just a couple of slots in the two tiers, or more even. Have like 3-5 different points of attraction in each tier and weight them. Primary points are twice as strong as secondary. You could even weight them within that tier. Have the first primary carry more importance than the third or fifth. Same for the secondary points.
I'm having a hard time tonight getting my mind focused because I'm really tired. After a good night's sleep I'm sure I can come up with more and better ideas. But this is a start.
