Is there other software that is similar to UE4?

As the topic.

So UE4 is the best software.

Sorry but this question is too broad, stupid and pointless. It is not the place to ask such a question. At the moment UE4 is the most advanced engine if you’re a beginner or you want to create something FAST. Unreal Engine 4 Speeds up the workflow for game developers. But it is up to you to decide what engine you like and what not.
