Unfortunately sorrow. In Flight sims I use mission editors a lot and over the years I have had the opportunity to use many, if not most, of them. Now I hate to say anything bad about ROF because on the whole it is so very good but I must admit the ROF mission editor is conceptually the worst I have ever used. I did learn to use it (requires proper tongue positioning, eastern black magic and the patience of Zeus) and I have created some missions but the pain vs. fun factor keeps me from doing much. My hope is that once they do all the good Battle of Stalingrad stuff they are doing they will re-hire the guy that did the original IL2 editor and let him do his thing.
