Hi. GuysFirst of all congratulations for the community, your doig fantastic job.I just started "studying" all about the add ons of Flight Simulator which make the game more realistic. I have seen many addons while i was googling but the most frequent ones use are REX, UTX, GEX, FScene, FSGlobal. I am abit confused as to what excactly each add on enchants FSX on. So far, i believe that :REX:Sky, Clouds,whether,runwayUTX:Roads, Bridges, Railrods e.tcFSGlobal: Mountains etcGEX: texturesFScene: Scenery/texturesSo am i asking:1) Is GEX and Fscene do the same thing?2) Are any of the addons listd above overlap with each other?3) Are all addons necessary, especially if i am interested on Flying in Greek Scenery?Thanks in Advance
