2D or 3D for your first games

Choosing 2D or 3D changes how much work a game takes. A 2D game places flat images, called sprites, on a flat plane. A 3D game needs models (meshes), cameras, lighting and a third axis for depth.

That multiplies the art, animation, camera and physics work. For first games, 2D usually means you finish sooner and learn the core skills with less friction. Unity and Godot are both good for 2D, while Unreal is built around 3D.

If you picked Unreal, keep your 3D scenes simple with template assets and focus on gameplay. The choice also decides which art skills you need later: pixel art or simple sprites for 2D, or low-poly modelling (simple 3D shapes with few faces) for 3D.
