This means if your game is a hit, you’ll need to share some of your success, which is something to consider.

Ease of Use is another important aspect. Unity has a user-friendly interface, making it suitable for beginners. It supports C# as its primary programming language, which many new developers find easier to learn. On the other hand, Unreal Engine uses C++, which provides more control but has a steeper learning curve. If you’re new to programming, Unity may be your best bet (unless you love a good challenge).

Adaptability also plays a role. Unity is ideal for both 2D and 3D games, which gives it an edge for indie developers looking to create various game types. Unreal Engine is often preferred for 3D games, especially those focusing on graphics, like first-person shooters and detailed RPGs.

Quick Checklist for Indie Developers:

  • What type of game do you want to make? (2D, 3D, or both?)
  • What is your budget?
  • How familiar are you with programming languages?
  • Do you plan to monetize your game significantly?

By answering these questions, you can better assess which engine aligns with your project type.
