What is a game key?

A game key is a serial number made up of a series of digits and numbers. This key is a personal proof of ownership that you can activate on gaming platforms such as Steam, Epic, Nintendo, etc. You can only exchange a game key once for a game, so that you receive the game in your account. Later it is always possible to download the game again and play it via your account, even if you have already removed the game from your computer. Game keys are also known as game codes, activation codes or product codes.
