Which digital format of Sigma Theory: Global Cold War should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

Why is the Steam Key of Sigma Theory: Global Cold War safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Sigma Theory: Global Cold War to your game library. The account format requires more complicated steps and is more prone to errors during activation.
