I fly FSX SE, and tour the western hemisphere in a 172. Just flying to places I've always wanted to see makes it interesting to me. When I shut down after landing, I save the flight and make it the default, so the next flight will be from the last place I landed to wherever I decide.
And, I think I may have found an Easter Egg...I landed at Sitka, AK yesterday, and after taxi to the pumps and shutting down, I heard loons honking! Coolest thing ever. I also use Skyvector to plan my flights. Make it real, and it stays interesting.
