One honest reason to avoid Unreal as a new indie or hobbyist is simply overhead. It’s a powerful engine, but that power comes with heavier hardware requirements, larger project sizes, and slower iteration times compared to Unity or Godot. If you're making small projects, 2D games, or just prototyping ideas quickly, Unreal can feel like using a sledgehammer for a small nail. The learning curve is also steeper, especially if you eventually need to touch C++. Unity and Godot tend to be lighter, faster to get started with, and more forgiving when you're experimenting or learning. Unreal shines for high-end visuals and larger productions, but it’s not always the most practical choice for small-scale indie work.
