@igazor I've never thought of improving the lives of other sims in town. By and large most people I associate with can't even understand why I want to have my households get to know the townies and why I want to give them makeovers and backstories and stuff! I like the sense of community. People keep telling me they just delete the randomly generated sims... something you don't have to deal with in Sims 3 unless you have sims being immigrated. Yet another reason to find some smaller worlds to explore. I think in a smaller neighborhood it would be easier to have a sense of community. That's my theory at least.
That mood mod sounds pretty cool. I really like the moodlet system in this game. There's a lot more of a motivation to keep them happy. I had a heck of a time keeping one of my uni students happy. I ended up paying for one of those expensive spa treatments. I think I'll try out the mild flavor at first. :D
