Drzewiecki Design, a Polish company that has been developing scenery add-ons for FSX and P3D for many years are upgrading some of their existing scenery packages to work with Flight Sim World (FSW).
At the moment, only a select few packages have been upgraded but we expect more to be released shortly.
Currently, New York City and Moscow Sheremetyevo are available. Seattle and other packages are to be released shortly.
You can view all of the payware FSW scenery add-ons here:
