Questions.
How much is it?
$12.99, one time. No subscription, and updates are included.
Is there a free trial?
Yes. You get 300 minutes of racing with the lights on, free, with no card needed. It is the same download as the paid version; buying just unlocks it with a key.
Which games work?
For the lighting, any sim you can see on screen: it reads the picture, so it is not tied to a list of titles. Flags and the pit limiter come from SimHub's game data, so they need a game SimHub supports. It was built and raced mostly on Le Mans Ultimate.
