I've not carried out a complete flight yet, but I've got all the 2023 scenery packs installed, and I've noticed a number of significant improvements that are not being talked about yet ...
1. New Navigation (flight planning) menu and options. I especially like being able to set the cruise alt here now! I like the new way of selecting way points and choosing whats displayed. Good improvement!
2. More high quality scenery. A few quick flights over places like Frankfurt, Paris, Brest, Lisbon, Naples was enough to convince me that theres a lot of better scenery to see, certainly in Europe. I like what I see over the Eastern USA as well, can't wait to fly my first flight from Dulles to JFK tonight!
3. The Swiss scenery looks to be new.... very detailed still, but somewhat more natural in tones, so even more realistic IMO.
4. 3D buildings, towers and columns etc in many cities. Ok, its a bit sparse but they are there (check out the City of London which is actually quite dense). A great step towards realism on mobile
So theres 4 strong new features in 2023 that I think make the extra money over 2022 very much worth it 👌
