Epic Games' Tim Sweeney announces Unreal Engine 4 is now available freely! The game developer promises they'll give you everything including all tools, all features, all source code, complete projects, sample code, and regular updates and bug fixes. The only catch is that Epic Games requires a 5 percent royalty fee on games and applications you release, but only after the first $3,000 of revenue per product per quarter so you only pay when you succeed.
Epic Games Founder and CEO Tim Sweeney talks about why Unreal Engine 4 is now free. Free for games, free for VR, free for architecture, free for film, free for education. Get Unreal at http://www.unrealengine.com.
