Firstly thanks to everyone who voted. I can now announce that the generation 4 heir is Danablu with 50% of the vote.
Also the world the family will be moving to is Barnacle Bay which topped the poll with 33% of the vote. I am pleased with this as it is a town I have not played with very much at all.
I am looking forward to playing this world, it looks so pretty. I will be tweaking some of the residents though. For example the Caliente sisters, Nina & Dina. I have discovered their personalities are different from the Sims 2 and this annoys me.
Overall great choice everyone, can’t wait for the new generation to start.
