I want to start learning game development and I would obviously come across this tool. So every where I went people mentioned Unreal Engine 4 to be a viable choice, I've tried a bit of Unity and now I want to try Unreal. Only issue I came across UDK and UE4, I downloaded UDK which turns out to be different from tutorials and I can't seem to find any info on that and besides I could only run the software once because after the first time it starts a game, I re-installed UDK I still get the issue, but anyways that's a different topic, what I want to know is whether UDK and UE4 are different and if they are, where do i get UE4, becauuse when I down UE4 (from - https://www.unrealengine.com/dashboard), it downloads a game launcher and no development tool. In case they are same, why is my version of UDK different fr
