http://charlotte.modthesims2.com/showthread.php?t=82193I found you have to be very careful what toys you give them, easels work better than pianos as they get too obsessed with pianos, etc.
tried some of squinges autonomous reward objects, the attration on them is a little too strong, so I have to but them on the edges of the lot...
http://charlotte.modthesims2.com/member.php?u=1454caution: since NL they also seem to cause a boolprop error but reset lets them continue. So they probably won't work on the leave it run all night type game.
I tried Inges business money making exercise equipment but they are way too attractive for this porpose, sims won't do anything else, so I had to give up on them!
There is also a hack that lets them gain skills from just "reading"....
I guess my biggest wishes for this goal is an easy way to set autonomy and attraction levels on more objects! (and an easel that they will automatically sell the painting when done!)
