I read this review from AVSIM-
It seems really compelling to me. One pitfall of VATSIM is the lack of online controllers, and this apparently can bring a similar level of realism offline and without losing your AI and in fact interacting with it as well. It can work with SIDs and STARs and has an OTTO function so I don't have to sit there the whole time and many other advantages that I'd like to have.
However, it's $44! Do you think, based off the review, buying that utility is worth the money?
