Nintendo received yet another stamp of approval for Brain Age this week, as U.K. gaming mag EDGE gave the brainy DS title the best game award at the Edinburgh Interactive Entertainment Festival. Even better than that were the words of EDGE editor Margaret Robertson, who said the pick was “the most overwhelming decision to date” by the panel of EDGE judges. “Who would have thought a game would make people want to do maths?” she said. My Brain Age is 23 and I still play occasionally, especially since I’m addicted to Sudoku. Anyone else?
