Both Run 3 and Run 3D focus on continuous movement, precise timing, and avoiding obstacles while trying to travel as far as possible. The main difference is that Run 3 is strongly associated with its tunnel-based platforming style, while Run 3D emphasizes a more traditional 3D running experience.
The gameplay of Run 3 combines running, jumping, turning, and exploring increasingly difficult tunnel levels. Run 3D follows the same basic idea of constant forward movement but can introduce different obstacles, environments, and level designs.
