Conglaturation !!! You have purchased a great game. and prooved the justice of our culture. Now go and get these add ons for it.

Flight Factor's 777 Worldliner Professional - Pretty complete 777 simulation. Adds another $60 to your cost though.

World2xplane - Free large scale scenery updates. Read the installation instructions carefully to understand how it works.

SkyMAXX Pro - Replaces the cloud generating engine. Visual enhancement. Lost cost add on.

Jar Design's A320 Neo - Nice A320 simulation.

Get an account at x-plane.org and start downloading lots of free aircraft and scenery and has a store to purchase payware products like the 777.

Disclaimer: I do not specifically know if the Steam version works with these add ons. They are totally missing the point of X-Plane if it can't run regular add ons.

Drew needs to get all this and have do an Unprofessional Fridays segment trying it all out.

If you want a Cessna I highly recommend Carenados CT206H, Best Cessna add-on iv'e flown by far.
