During GDC 2015 Epic Games announcedthat Unreal 4 is now available for everybody for free from game development, education and visualization to VR, film and animation.
Epic Games is going to make profit by the games and applications based on Unreal 4 – that of 5 % royalty of gross revenue after the first 3 000 $ per product earned by a third-party developer.
According to Epic Games’ Tim Sweeney, Epic Games’ goal is to give the customer absolutely everything, so that you can do anything and be in control of your schedule and your destiny. Whatever you require to build and ship your game, you can find it in UE4.
