One way to see things in the sim that you have never seen before is to accomplish a round-the-world flight with real world weather and time. If you do it in something lower/slower like a turbo-prop, you will see terrain, lighting, and weather combinations that you have never bumped into, and it is surprisingly interesting. I finally broke down and did this a few years ago (used the real air turbine Duke). It was the most interesting set of flights I have had in a long time. Especially when I ended up in parts of the world that I rarely explore. Having a tool like FSTramp is helpful for planning distances between airports. Took me about 2 months to finish the flight in real time. I would save my flight each time I reached a destination, and my next flight would pick up from there.
