Wolud it be possible to add in a check to prevent Marco Polo wants when there is no swimming pool on the lot and fishing wants when there's no pond? With FT and a bunch of Sims who are growing their own food, the fishing wants in particular are getting obnoxiously intrusive.
Answer: If it was, I'd have done it already. Alas, those wants are checktreeless, meaning they refuse to die.
Would it be possible to burninate the Marco Polo want out of existence? Although that might be out of scope for this hack, I am sick of it clogging all of my sims wants.
