The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format.

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.
