Nintendo showed up this weekend at a convention one probably wouldn’t expect to be encountered by video games at: The AARP Life@50+ convention in Anaheim, Calif. The company was showing off its Wii in force, demonstrating to the 20,000 attendees that the Wii wasn’t just for kids. It also had demonstrations of “Brain Age” for the DS, with Nintendo operatives wandering the grounds wearing badges that read, “Ask Me My Brain Age.”

I believe this will go down as one of the most brilliant moves of any gaming manufacturer. Its an untapped goldmine of consumers. Retirees with gobs of cash looking for more entertaining ways to spend their time. But the real beauty is in the fact that many of these retirees have grandchildren who will embrace the technology even further—brilliant really.
