Have you finished a 10 generation Legacy? (or more)

I started one but I got bored when I got to the third generation. It occurred to me that everything that I had done with generation 1 and 2 and was going to do with generation 3 in terms of aspirations, careers, and skills could be accomplished by one single Sim. I also found that I had no interest in playing any Sim but my designated founder. So I opted out of playing legacies in order to focus on the accomplishments of one Sim instead of generations of them.
