Something I've been thinking ... possibly have Nicole or the Crown Jewels have the same affect on Investors as the Hustle Queens. That would give them a bit more ... oomph ... early in the game.4 - A filter to find the Crown Jewels once the girls pool is wide enough to forget who's who. Maybe there could be different "jewels levels"? Like bronze, silver, gold, where they provide different benefits and have different costs as well. Or require different tasks to unlock them... just thinking loud.
Getting to 100 popularity and landing a Crown Jewel when you're only at the late dancing or pose stage makes using the CJ a bit of overkill.
Just a thought that hit my pea-brain while I was struggling with no Hustle Queens to be found.
