Could this be your life?

I've often blathered about a vision for a sort of simulator for visualizing and "trying out" future lifestyles. It may become the focus of my masters thesis if I can buckle down. A career plan builder is a step in the right direction, but it doesn't really go far enough. Could This Be Your Life? is an interesting take on the concept. It's not exactly a rich experience, but yields some interesting results.
