also depending on which traits you have will depend on what activities they do such as paint as an art Sim or read a book etc
I wish this was true. Well it sort of is but I noticed that certain objects still have a ridiculously high advertisement to sims overall. The computer for example. Regardless of traits all sims have an unnatural attraction to play games on the pc which is incredibly annoying.
I'm not a modder but I think the way traits work is that it affects the level of advertisement certain objects have to sims having that particular trait. I noticed that for certain traits and objects this works very well. I think the culprit could be objects that provide "fun" since the sim scans the object to fulfill the fun need which is non-discriminatory which trumps the trait system which is.
now how about altering the game to think painting, playing chess were needs
It sort of already acts this way. I had several sims who would work-out and read autonomously constantly. Actually one of my sims (simbot even) maxed out the athletic skill despite me trying to sabotage him from doing so. At a certain point I just gave up and let him be (when he reached lvl 8 of that skill mind you).
See, that's why you need to be more like me. It's pretty obvious that I'm a big, terrible, mean person. If somebody says I am a terrible, mean person, I will just grin evilly....and be mean to them! It's good to be bad. *J.M. Pescado*
My sims also do 'elective activities' on their own. The bookworms DO reach for a book if there is nothing else to do and the couch potatoes DO sit in front of the TV. They do the laundry on their own, clean the house, and all sorts of things. All I have to do is stop micro-managing them. Again, not connected to wishes but still they keep busy. I rarely have a sim who stands there and does nothing. I am not sure why my game seems to be different from some some of you. I have a young woman with a baby married to a firefighter. I sometimes just leave her to do as she pleases while I go off and watch what is going on in town. She never idles...and is always doing something when I come back to her. And once again, the other people in the 'apartment' are also busy.
I find the game or more likely, Twallan's SP, does a pretty good job of pushing the sims to do things related to their skills/professions. With the autonomous romance mod in place, they also flirt with each other without any help from me. I have learned to let my sims make more choices. Now, I used to control their ever whim and found the game boring and predictable. I think the trick is to not feel as if you have to micro-manage everything.
