However, you can try these solutions:
* Adjust your monitor's brightness: The easiest way is to change the brightness on your TV or monitor itself.
* Use your graphics card settings: If you're playing on PC, you can usually access brightness settings within your graphics card's control panel (e.g., NVIDIA Control Panel or AMD Radeon Software).
* Adjust in-game options: Some games offer brightness settings within their menus, although this is not the case in Lego Star Wars 3.
* Change the environment: If the game is too bright, you might try playing in a darker room to reduce the overall brightness perception.
Unfortunately, there's no official way to adjust the brightness specifically within Lego Star Wars 3.
