Starting September 8th, game rental service GameFly will launch an all-new client app that will allow subscribers an "unlimited PC play" option to download and play as many Mac or Windows titles as they want from a library of over 8,000 -- and growing -- titles. The new service will also serve as an online "game store," offering purchase of over 1,500 titles and pre-ordering new console and computer releases, an option to buy used games, a social aspect, and more.
