I have all of FC Scenery. I also had all of Megascenery with the free autogen for it. FCS is much better, and the textures are very good. They update the scenery with newer technology which is nice to have. For example, I have version 1, then version 1.2 came out with a new autogen. Now version 2 is coming out with 2024 data and seasons. I do donate for any of the upgrades because they are well done. I used Scenery editor version 1.9 to manage the scenery and load what is needed for the flight. I used m.2 SSD 4th generation with a USB 3.2 adaptor. 4TB is not expensive these days, I think total space is around 12TB. I enjoy P3D 6 very well and it is very stable, with FC Scenery I have everything I need. I just fly to airport to airport with many aircrafts. I am looking foward with version 2 for all his scenery as it comes out.
