Today in Gaming - 4/7/11: 1UP Gameathon and GameStop's Facebook Store

As of this writing, 1UP's Gameathon is approaching the 12-hour mark. We've played the likes of Rez, Gitaroo Man, Burgertime, and Gallop Racer 2003: A New Breed. (Yeah.) We'll be continuing to play games until Friday at 10am Pacific, so be sure to tune in between now and then to take part. Of course, the entire point of this is to raise money for Red Cross and the relief efforts in Japan, so if you can spare any money, please donate and spread the word.

Today's highlights:

• Valve is releasing a Portal comic tomorrow filling in the series' backstory.
• A Mass Effect anime movie is coming next year.
• New details on the in-development SSX game, which is no longer called Deadly Descents.
• Comedy Central is getting into the game-making business.
• Get in shape like a UFC fighter.
• This Guy Makes Awesome Video Game Props
