Game engine maker Unity has launched a developer program to help its users build experiences to run on the forthcoming Apple Vision Pro.

Following Unity’s pricing gaffe, GameMaker is making its engine free for non-commercial use, and switching its professional license to a one-time, $99 fee.

The goodwill that game engine developer Unity burnt over the last week with its bizarre and retroactive pricing demands are going to be a problem for not just the iPhone, but Apple Vision Pro too.
