I believe Aerofly FS2 is on the way to a bright future, but there is something that can limit it from achieving true greatness. The lack of 3D water is among the major obstacles.
I have no doubt flight simulation is progressing towards more and more realistic modelling of our planet earth, something like Google Earth VR, but more detailed, and more alive. Then we can't imagine the lack of 3D water in this virtual world. The static satellite image might be enough for today, but will be a bottleneck of the future.
