Honestly, the fact that it is free is probably the best for me. I'm not a game designer and I would never have had the need or the desire to pay a large amount of money for this program, but I've learned a lot being able to use it for free.

Graphic Quality, blueprints, nodes, C++ integration, unexpensive, high quality in a few time, realistic lighting, a lot of interesting tools to increase the productivity, community grow up and a market.

I began using Unreal, coming from a Unity background. Unreal provides a high-end quality to projects, in terms of graphics. Games made in Unreal look amazing. Furthermore, it has a low-level barrier for beginners who might have not that much experience with programming. The Blueprints Visual Scripting system allows developers to work, without too much hassle, much drag-and-dropping nodes which connect and that represent the overall logic of the different elements in the game.
