The Adam And Eve Challenge

Honestly, I have a hard time making it through 10 generations, much less 50. 30 sounds more manageable, but I don't know if I would stick with it that long, especially if I finished buying all the community lots before then. Is there a specific goal that we should accomplish by the end of the generations?

Maybe start out with 250,000 and the challenge would be to have a full town with every lot occupied and every community lot available in the simmers game placed somewhere in the town and owned by the family?
