Their action effectively removed games from user accounts, blocking them from being launched remotely. The story goes like this: Just a few weeks ago Ubisoft revoked the game keys of an unknown number of Uplay members. The secondary games market has been in the headlines recently because of a small scandal involving Ubisoft game codes purchased through Electronic Arts' Origin service. So how does this gray market function? What are these secondary markets like? Who sells here, and who buys here? And where do these codes come from? Ripped from the headlines Steam keys, Origin keys, gift keys and even codes from the back of pre-purchased retail game cards - these storefronts have it all. On these and similar marketplaces you can pick up just about any game you want, including triple-A titles, often at huge discounts. Gravity Ghost isn't the only title on sale at Kinguin, or at its competitor G2A. We picked up our key on the secondary market, also referred to as the 'gray market.' That's how we saved close to $3 on the purchase. Or rather, those are the official places to buy it. The indie game is just a few weeks old, and currently the only place to buy it is through the Humble Bundle store or Steam itself. The Steam key for Gravity Ghost, the new release from Ivy Games, cost Polygon $12.44.
