1UP, they're not just a games site. They in the business. The rental business. Starting soonish, every time (every single time) you hit up a game page on the site, you'll also be given the option to rent and/or trade said game. An option I'm guessing is dependant on availability.

As a polite gesture, their partners in this bold new venture, Gottaplay, will feature game info from 1UP on their product pages. Which all means...they're not really "partners" at all, Gottaplay just got a sneaky new way of advertising. Very clever, Gottaplay! Luke Plunkett
