Started reading this at the beginning and now am caught up. I'm a female and I loved the Paradisa set and hated the Belleville set. I only bought one Paradisa set while it was around, but that was because that was all I could afford to buy. There weren't enough cheap sets in the line, especially if your allowance was only ten bucks a month! Do you know how many pirates and castle sets I could get? Or at the time lots of race car impulse sets.
During the time I was really into Lego, I was all about the Forestmen. I loved the little green guys with their trees and pointy hats. They were super cool too me. I also had a lot of pirates, but that was a price factor.
If I was to build a Girls theme now, I would make two aimed at different ages. I would go with what they are putting out for an early age group and then about age 8 or so go with a minifig scale series. Now on the minifig scale series, I would want to see the following themes:
Amusement park, Zoo, Vet CLinic, Open air mall with different stackable shops to build up mall, Concert Stage with band, singers, fans, public swimming pool, beach resort/houses, Internet Cafe, Duck Pond/park, a molded chicken, a pregnant lego minifig, a baby, baby animals, and
College theme
-fountain
-library
-football game w/cheerleaders
-dorms
I also would like to see a city subset of camping, maybe even with a boyscout and girlscout camp/troop. I also think a lot of food places would be good like Sushi/Teppenyaki Grill, Burger Joint, Taco Stand, Farmers Market, etc. And more recreation themes like Golf Course, Baseball stadium, and Football Stadium. A Rodeo set could be fun! For the Golf set, could have Golf Cart, Club House, Club Pool and Spa, and some real fancy Country Club houses and dances.
The most important thing to get girls interested in sets is to have female minifigs in the set. Girls can be cops, construction workers, bad guys, military, fishing, store clerks, pilots, baggage handlers, etc. I mean, c'mon, Girls do it ALL! ;) I will buy one set over another if there is a girl minifig in it.
