FSSM regarding graphic basic scenery is the best simulator that I knew till now. for my opinion no need to add others stuffs . then to take risk like was too often case with anciens versions to make heavy and unstable generating program crashs … was and staying stunned by the basic general quality about scenery details elevations mountains / grounds, more weather effects, keeping one excellent framerate I never did dreams about more , sure I did get some landmark availables really enjoyables . but existing airports runways are for me very acceptables and credibles, I no feeling need to add cars and buildings basics are already greats …
My lone reproach is to don’t found vintage airplanes can’t wait to found propeller liners and others light legendary propeller at my opinion that lack cruelty … (and maybe to can’t see replay sequences)
