Planet Formation theory has come a long way. After initial miss guidance from our own solar system, we now have compiled at last a plausible story how dusty-disks around young stars turn into planetary systems. The models have become so sophisticated that we cannot only test various model assumptions about the various formation steps against the observed distributions of Exo-Planets --- we can now also ask for correlations between the properties of the host star, especially mass and chemical composition and the characteristics of the resulting planets in terms of mass, orbit, and chemical composition. This opens a venue to determine how planet formation relates to chemical evolution, and addresses the question when the first planets in our galaxy where born.
