Well, no one answered my question. So I will repeat it. Does XPlane 10 come out of the box with the entire world like FSX?
Sorry, I missed your question first time.
Yes, xplane comes with the whole world on 8 dl dvd's. You don't have to install all of it . Total install is about 65 gb I forgot the exact amount.
Roads are based on open street map data and airport runways and taxi ways are all pretty accurately placed with elevations and sloping runways if applicable. But don't expect any airport buildings except for Seattle Tacoma. There is plenty of autogen. But no landmark buildings and no airport buildings. There are tons of freeware to fill all this in and recently there has been a bunch of payware airports to fill in some of this. Rural areas like alaska or mountain areas look really nice. Urban areas, not so much. I've converted a lot of my fsx scenery to get some of the cities to look like they should.
Xplane is a great flight sim engine but right now is far from complete. In a year or two it should be the go to sim, but right now fsx is a more complete out of the box sim if you don't want to spend any more on addons.
There is also a big update coming the end of the week to fill in some of this but I don't know exactly what's included.
