How do I activate a game key I've purchased?

The method to activate your game key varies by platform. Typically, you will need to input the key into the designated area to activate the games on your platform. For instance, on Steam, select 'add a game' located at the lower left corner of the interface, then choose 'activate a product' and enter your key.
