The affine formulation of General Relativity is presented. From this point of view the cosmological constant is not an option but a necessary element of field dynamics. Moreover, it is obvious why the Einstein's attempt (1925) to unify gravity with electromagnetism based on the concept of an asymetric metric tensor "g+f", could not work, while a different, entirely new unification pattern looks natural. Finally, there is a room for dark matter, not just by "adding new terms" to the existing theory but by taking into account the natural goemetric structure of spacetime.
