Lot Traits: Do you change them to fit your current household?
See headline. Basically, assuming you use them at all, do you "play fair" and stick to them or do you change them to fit your current household ("good schools" for kids, for example).
It depends on what the traits are. I always change Needs TLC or Gremlins, but I like to keep traits Cursed and Haunted around because they keep things interesting.
