FAQ
Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. That's why we only list sellers with buyer protection.
Which key region should I pick?
Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
