The differences are between the regional versions and the Global version. Regional versions are slightly cheaper and only contain a limited amount of the world scenery (such as only North America).
IF you purchase X-Plane through X-Plane.com's store, you will receive the full global version with all the world scenery. You just have to pick if you want to install and unlock demo mode with DVDs or a digital download key.
Do NOT pick the option "​Global Scenery Upgrade for X-Plane 10 Regional Editions".
