We've seen some charity gaming marathons in the past, but most (like the Mario Marathon) tend to stick to a single series. Starting tonight, GameToAid.org will be playing a wide variety of games over the next 72 hour period for World Youth International. Two teams of gamers will compete to finish games first, and the games will include Black Ops, Ocarina of Time, Conker's Bad Fur Day, Perfect Dark, Portal, Ratchet & Clank, Gears of War 2, Goldeneye, and more.

It won't start until 7:30pm CST, but the guys are messing around with some Black Ops in the meantime if you'd like to check it out. You can catch the entire marathon at gametoaid.org, and they have donation links on the site.
