Purchase payware planes like aerosoft a320/a321, pmdg b747, virtualcol q300, etc. then purchase Ezdok Camera. Also buy any addons that can make the game more realistic. Then make full flights with these payware aircrafts while looking at the beautiful skies. You could also make cinematic views. But if you wanna make people interested at fsx, make FSX Films like what JRSchipol and FSXAviation1 used to do in early 2010s. If you want to something cheap, buy ChasePlane, it's half the price of Ezdok. Download Project Airbus A32x, Project Opensky B777, DreamWings Q400, etc. Download ENbseries, HDE v2, FS Water Configurator, TreeX, etc. So even if you fly with freeware aircrafts, the game would still be accurate to real life.
