There are a fair number of people that enjoy “flying like the old days” (like I had to do many, many years ago!), and it’s still very possible in the sim. But as I’m sure you’ve noticed, many of the planes/systems are more oriented to flying routes in a more modern way.
Periodically, I’ll set up a route for my TBM930 solely based on VOR/ADF facilities and enjoy flying that way. But it requires more preflight route planning, and gets frustrating sometimes, although rewarding!
If you ever want to fly some “older-oriented” routes in the U.S., I’d recommend this thread:
The originator of the thread has developed a very good system that replicates the navigation environment of the early 1950’s.
