The most world-class game engine to date, Unreal Engine 4 gives you the power to do more than ever before. Bring your creative visions to life directly in game without programmer assistance via the new Unreal Kismet.
I love this engine. Everything about it is just glorious with insane amount of things to grow. It dropped its ever complicated Uscript and just went with C++, dropped kismet and created blueprint. Plugins, game type tutorials, everything is free. What more do you need?
