Remember how Nintendo said you could plug in other devices into the Wii remote? Only the Retro Controller and Taito’s Densha de Go! Shinkansen EX: Sanyou Shinkansen Hen have taken advantage of this feature so far. To be fair, other Densha de Go! games come packaged with their unique controller, which is designed to simulate driving a bullet train. In the video below the Densha de Go! Wii controller plugs directly into the remote and it looks like it makes the game a more immersive experience.
