"The 1up Gameathon for Alex is just like a 5k race - except instead of running, participants will be playing video games for ten straight hours on Saturday, February 8th, 2014," says the official website. "Everyone involved will be actively raising money through pledges from various donors. For example, one person may pledge $1 per hour played, or a simple one-time donation."
As for where the money's going, there's good news and bad news. The good news is that Mr. McGuinness is doing quite well. "Through the excellent treatment of doctors and the miracle of modern medicine, Alex is on the road to recovery and has maintained an amazing and inspiring attitude throughout his treatment." The bad news is that here in the United States, healthcare for cancer patients is very expensive. This event hopes to alleviate some of the debt incurred by McGuinness during his recovery.
