Context: Today there are a lot of different kinds of game engines to choose from, but is one of these engines more suitable for a developer with a beginners' experience in game development? Objective: This is something we explore in order to help teachers choose a suitable engine for teaching game development to beginners.In this study, two teams of two persons each compare two of these engines, Godot and Unity. Method: We conducted a study, consisting of six iterations, to observe the development of a prototype game using the two engines. We collected data during the development of the game using a think-aloud protocol and a questionnaire, and after the development using a questionnaire that included the SUS scale for assessing the overall usability of the game engines. Results: The Godot engine have been focused on completing their documentation and the documentation is somewhat directed to more experienced developers. In comparison the Unity engine got more solutions outside of the documentation and also got their own special guides towards beginners.Although Godot engine got a more simpler GUI which will be easier at first but as the tasks became more difficult this became more of a disadvantage and some solutions were not found easily among the documentation. In comparison the Unity engine got more menus and can seem a lot to a beginner but became to be more helpful the harder the tasks became and even though most solutions were not found among the documentation, there were enough information from other sources to solve all problems with an easy search.Neither of the engines provided with a lot of helpful information within the tool, although the Godot engine had some cases where the tool would let the developers know a certain component was needed. Conclusion: Our main conclusion is that Godot is a good entry point into game development but as the tasks gets more difficult students would need the teacher’s help in order to solve the tasks as easy as with Unity. In contrast, Unity starts more difficult but as tasks gets more difficult Unity have more solutions online, which makes it more suitable if students are to develop on their own.\\This study is rather small with only four participants and this limits the results, for future studies it would be best to have more participants.
