FSX/P3D. I am really looking forward to adding Nagasaki to my collection of Asian destinations and if you read my recent review of Manila, you already know my feelings about this developer and the rapid acceleration he is progressing in the overall quality of his projects. Nagasaki not only displays some terrific quality, but the latest shots show massive improvements in the very areas I said needed improvement with Manila. I am very impressed and yes, internal modeling is very thorough throughout the terminal. I don't have it yet but i'm impressed. Expect a live stream upon release! And go read my manila review! PacSim is on the up & up! Seriously.
