Frequently asked questions

How do I activate One Upon Light?

You'll receive an email with your Steam key immediately after purchase. Open the Steam client, select 'Activate a Product' under the Games menu, and enter the provided key. The game will then appear in your library ready to download. No additional steps are required beyond standard Steam account login.

What does worldwide activation mean?

The licence key activates in all countries where Steam operates. There are no geographic restrictions on where you can redeem or play the game. The same key works globally regardless of your account's registered country, provided Steam services are available in your location.

When will I receive my purchase?

Delivery is instant through automated email. Check your inbox (and spam folder) for a message containing your Steam key. The email typically arrives within seconds of completed payment. If you don't see it, contact support with your order details.

What happens when the licence term ends?

This is a lifetime access licence with no expiration under normal circumstances. Your access continues indefinitely through your Steam account. The only exception would be if Valve's Steam service terms change in ways that affect licence validity.

Is this a legitimate resale?

Yes, all keys are genuine software licences acquired through authorized distribution channels. You'll receive a proper VAT invoice with your purchase where applicable by law. The seller provides activation support if you encounter any issues redeeming your legitimate copy.
