When a player installs the game, they are prompted to enter the activation code to verify the authenticity of their copy. This process ensures that only legitimate copies of the game can be played, helping to prevent piracy and unauthorized use. Additionally, the game may also require periodic online verification to ensure that the copy being used is still valid and has not been tampered with. **

Overall, the main difference between these three types of iron lies in the methods used to refine and process them, resulting in different properties and applications. **
