I mostly played the ‘traveling salesman’, stringing together as many airports as possible, covering as much ground as possible. Capitals were all a must visit, as well as major landmarks and PG areas. And everything marked with a star on the world map. I wrote down all the airports and ICAO codes to visit in order and then see how far I would get each day. I updated the list about once a week.
While flying (on autopilot mostly) I would be looking up where I was flying to or flying over. It was all about discovery, I didn’t do a lot of research beforehand, mostly after visiting. Only when I wasn’t certain which way to string airports together I would check out which path looked more promising for sights.
For Antarctica I checked out online resources to string a couple bases together, as well as for a few other places that don’t have an airport in game. Little navmap is very helpful for flying to coordinates as well, simply point the plane at where you want to go. (I don’t know how to enter GPS coordinates into the GPS…)
The 32GB was very helpful since I had tons of tabs open in Firefox, little navmap running, paint shop, and other stuff I was multitasking. There are a lot of empty stretches in the world, plenty time to do stuff while on a long journey to the next natural park or signs of civilization. And of course there are long flights over water as well. Alt-tab, check on progress, check the fuel and how the plane is performing, alt-tab back to work or research or updating the thread.
