Dovetail Games just got in touch to let us know that they've finally entered phase two of the development of Flight Sim World. What does that mean exactly? Well, the game is leaving Steam Early Access after eight months, and therefore the game just been updated. Players are getting some new aircraft (including airliners), IFR and ATC upgrades, and a bunch of general improvements across the board. Patch notes for Update 16 and a general open letter about the shift out of early access can be found here, which details the changes and points out that players are getting dynamic and live weather effects as of February 1.
