It's now official. As the Atari 2600 was defined by its games featuring food and mazes, and the NES was defined by its 2D platformers, the Nintendo DS will forever be remembered as the system that had "all those f*cking games about dogs". Sometimes it's dogs made out of tea leaves. Other times it's dogs ready to do serious battle. And of course, there are the Dogz. It's all proof positive that today's developers just can't go more than a month without announcing a new dog-centric DS game.
