I went with "Other" since I don't really have a backlog, but I do have a forwardlog. I've already played the crap out of all the games I own, now there's nothing left but to look forward to the games I intend to get in the fall.
Going to pick up the PS4 version of Diablo III and play with some of my coworkers, but as I've already played it a lot on my 360 even that will be just to pass the time until October when Alien Isolation and Dragon Age come out.
In the meantime, I'm going to be buying a new graphics card so I can play Skyrim on the PC (picked it up during the Steam sale). Again, this is a game I've already had my fun with on the 360 but now I've got a chance to play it with mods! Beautiful, glorious mods!
