If players are comfortable sacrificing a physical box copy in exchange for the speed and convenience of a digital product, GameStop's service will allow them to purchase and download games, trials, expansions and various add-ons in the comfort of their own home. Players will be allowed to install the game on one to three PCs, depending on the product. Unfortunately, because the service is being handled by a third party, GameStop gift cards and certificates are not accepted as payment.
GameStop's downloads page features a number of MMOs for purchase, including Need for Speed World, LEGO Universe, Aion and Age of Conan. If you haven't given Final Fantasy XI a whirl, the Ultimate Collection is on sale for $9.99 in both boxed and digital form.
