Why is the Xbox Key of Killer Instinct safer than the account format?

The Xbox 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 Killer Instinct to your game library. The account format requires more complicated steps and is more prone to errors during activation.

What issues can arise when activating a Xbox Key of Killer Instinct?

Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries. Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer. If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.

What guarantee do I have that the listed stores are reliable?
