My mind is blown, people.  Blown!  Sega has unveiled a teaser website and Nintendo has the press release for the first (authorized) video game that stars both Mario and Sonic the Hedgehog.  Can you believe it?  The Mushroom Kingdom and Mobius will collide in Beijing, China for Mario & Sonic at the Olympic Games.

In Mario & Sonic at the Olympic Games, players will compete in events that take place in environments based on the official venues of the Beijing 2008 Olympic Games. Using a supporting cast of characters from the amazing worlds of both Mario and Sonic, gamers will be able to compete as or against a range of lovable personalities including Mario, Sonic, Luigi, Knuckles, Yoshi, Tails and more. Innovative usage of the Wii and DS control systems to maneuver a favorite character will allow players to race the likes of Mario and Sonic down the 100m track, engage in exhilarating rallies in table tennis and churn water in a swimming heat, all while competing for the much sought after gold medal.

Assuming this isn't some kind of early April Fool joke (and I really hate those), I'm having a hard time wrapping my brain around this announcement.  I mean, sure, this is the legendary meeting that so many gamers have hypothesized about for years, but to actually see it happening... I just can't make it compute.  It's like some kind of logical paradox.  This game shouldn't exist... and yet it looks like it does!  I think I need to go lay down and process this information for a while.  We may be just a step away from cats and dogs living together and mass hysteria.
