World Manager + Simple Create a World Tool - My concept

I love this idea! I always want to customize my sims worlds and am frustrated with the default lots that cannot be customized. I for one would love to completely customize my worlds. I would love to be able to write my own stories and create my own world themes. It would be so awesome to have the ability to choose not only the weather, but the agriculture types in a specific world. To choose the building styles to meet my vision and role playing if I choose! Please EA, give this post some serious consideration!
