Listed seller price shown — payment fees may vary by method.
Offers that are not a key (Gift) — show (1) Gift: the game arrives as a Steam gift and works only in the region it was bought for.
These are not ordinary keys. A gift is usually region-locked and arrives through someone else's account — if the region does not match, the game will not activate. An account means you get someone else's login: the game never becomes yours, and it breaks Steam's rules. A DLC or a bundle is not the base game. That is why none of them count towards the price at the top of the page.

Is Steam an official store or a keyshop?
Steam is an official store — keys come directly from the publisher or an authorized distributor.
Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's 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.
