Which digital format of Cities Skylines Mass Transit 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.

If I buy the account format of Cities Skylines Mass Transit, will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Why is the Steam Key of Cities Skylines Mass Transit 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 Cities Skylines Mass Transit 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 Steam Key of Cities Skylines Mass Transit?

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.
