Environments for creating video games are software tools that make it easier and faster to create video games. However, it is very difficult to decide on a specific environment for creating video games, because not all environments are the same. They use different programming languages, functionalities and have different possibilities. Some environments are simpler and faster to learn, while others are more complex requiring more effort and time. Such doubts make it difficult for the user, especially the beginner, to choose an environment for creating video games. Therefore, this paper tries to resolve the doubts by comparing three popular environments for creating video games - Unity, Godot and Unreal Engine. This work will attempt to describe the basic components of each environment and list their mutual similarities and differences. In order to achieve a successful evaluation, three simple video games were created for the purposes of this work, were each one was created in one of the environments, in such a way that they are as similar as possible. This demo project evaluated the following parts: programming, program interface, functionalities (materials, terrain, particle system, animations, and user interface) and image rendering.
