FSX/P3D. To be honest, the FSAddon version of Tel Aviv's Ben Gurion by developer David Rosenfeld (who is currently developing Malpensa) was quite good. But where it lacked was in the detail department as it pertained to other parts of the airport such as the logistic, maintenance, and general aviation areas which always felt a bit rushed to me.
Today Mathijs Kok Announced a wholly new version will be published via Aerosoft. However, what was not mentioned is who the developer behind the project is. I'd really like to know. Only a render of the tower at the moment. Thanks to ADX reader Michael Holzberg for the tipoff!
Update: Apparently the dev is Gaya Simulations.
