What is a Steam key, and why buy one?
A Steam key (also called a “CD key” or “activation code”) lets you redeem the game to your Steam library without buying it directly on the Steam Store. They’re commonly sold by official partners (publisher stores, approved retailers) and key marketplaces. Once activated, the game behaves as if you bought it on Steam—updates, cloud saves, achievements all work normally. Always check region restrictions and retailer reputation before purchase.
