What is Platforms?

Platforms are the devices a store's keys, cards or credits redeem on, and that list decides whether a purchase is usable for you. A key bought for the wrong platform is dead money, so check before you pay. Activision and Aussui carry the widest reach, covering PC, PlayStation, Xbox, Nintendo Switch and mobile. 4Netplayers covers PC, PlayStation and Xbox, 2Game lists PC alone, and AirGPU pairs PC with mobile. Narrow coverage usually narrows the catalogue to match.
