Needs some fine tuning right now. It's very much a first draft of a new system.
If you didn't like the old mood system, you probably won't like the new one either. The main difference is that moods are now controlled by five "physical states" (comfort, beauty, stress, pain, pleasure) with each device or event producing different amounts of one or more of those states rather than having it's own effect on moods. Girls now have individual personality quirks (like masochist or tough) that respond differently to the five states, so what works for one girl won't necessarily work for another.
