Looks interesting, but with no ATC then initial reports are that it does stuff like have flights arrive in-front of you taking off when on finals etc.
I think they’ve tried to balance ease of use with good performance, but as someone that buys all of these things, on a quick look it seems like World Traffic 3 is probably still king on X-Plane at least. The trouble with WT3 is just that the ATC commands don’t appear in VR, plus the hooks for other stuff with voice output/recognition like Pilot2ATC don’t exist. WT3 also takes a bit of setting up, as you need to register the flight plan, but if you do use its ATC then you do get good and more realistic AI separation.
I hate using these traffic things and then seeing aircraft fly in-front of me…
