I'm building a fictitional solar system around an F5 star. I have been told that this would not be a good choice because of its low metal content. So I need to know if the star's nature would inhibit life developing, and if so, are there any loopholes I can use to explain life developing despite the difficulties?

PS - Would there be any important statistial (mass, density, etc) difference between two almost identical stars with different luminosities? Say, a G4 III and a G5 III?
