Donate to Child's Play charity during our 24-hour marathon!

This Friday we're sitting down for 24 consecutive hours of mulitplayer madness. As with the past two marathons, we'vealready encouragedyou to play along and stay up as long as you can, but this time we've got one more favor to ask - donating to the Child's Play charity while we endure a full day's worth of gaming. We've set up this ChipIn widget to link to the charity's PayPal account, so rest assured any money you drop in goes to worthy cause. It's embedded below, but you can also headhereto donate directly, or wait to donate once the marathon begins at 5pm PST tomorrow.

As added incentive, donating more than $50registers you for a chance to win any five games we're playing during the marathon.
