I think you misunderstand the post. Its not that its not fun, but rather there is a different option that exactly provides what you seek. Do you have SC on your SSD? If not, recommend you get it. I have ED, SC, and NMS and between SC and ED, its interesting the overlap between the two even now. The SC mobiglass vs the ED station services have so many similarities, even the little UI visual flutters and navigation noises are the same. What you and other describe in their desire for "space legs" is EXACTLY what SC has....exactly!
Again, its not that I "dont want it," but rather I already have it, in a different but similar space game. Why have two games exactly the same? Its a waste of time and resources for FG in ED, plus its a huge effort and frankly a distraction, and honestly/hopefully FG knows this. ED is what it is, and there is plenty of room for growth as a space flight sim. Keep it there and leave the FPS to SC and NMS, or others. ED to me is kind of like the next step from Space Engine (SE) where SE provides the realistic expanse, but does not have gameplay. ED has SE, but includes gameplay in the flight sim and persona build angle. FG/ED and future seasons should stick with this angle. As noted, a new alien enemy will be introduced to the ED galaxy which I am quite looking forward to (one of the main reasons I bought ED among others). It introduces all new missions/experiences with no need for space legs. Further ahead, who knows, but there is plenty of experience yet that could work within the existing FD/ED mechanic of spaceship sim only.
And if you want space legs, and FP experiences described, that is EXACTLY what SC has/is. Become a backer and get it there..., no harm in that you know...
