Hey t0ni,
that's a real nice collection you've got there!
Are you playing casually with your gamepad/controller or just keyboard and mouse?
I remember that I had some struggles with my controller as I had way too many things installed that conflicted with eachother due the key mapping.
Did you ever think about using some extra hardware like Elgatos StreamDeck? I could see how it raises the immersive experience by using those extra buttons for the sirens or radio etc.
P.S Thanks for the real nice overview, gonna saves me some time for browsing around lol
