FS-WWI doesn’t have the ravishing looks or rigorous realism of Rise Of Flight or Over Flanders Fields, but in other significant areas it more than holds its own. The Gotha-sized installer (1GB) includes hundreds of thoughtfully wrought sorties covering everything from dogfights and bombing raids, to balloon busting and carrier ops. The ride selection is Hendon-huge, all the usual suspects rubbing wingtips with exotica like early war monoplanes, airships, and landships. Not every machine is sculpted or skinned as beautifully as the Bristol in the first pic, but a good many are.
