This is not necessarily a bad thing, it depends on what you want from a flight simulation. The carrier activity is second to none in superhornet, very busy with lots of people and planes going on. The graphics, as mentioned above are slightly substandard. They are not as detailed as modern sims now provide. There is lack of relief on the land and lack of detail in land graphics.
Buildings look a little sparse.
The positive side of this is that superhornet runs at a higher framerate than Janes, thus looking more realistic than Janes. Sound is okay, nothing to write home about. I don't like the cannon sound, but not too many sims have a good sound for their cannon.
