Many of us here are Nintendo fanatics, so much so that we'll line up to buy a system at launch. Others are more careful about their purchases, waiting until the right circumstances before committing to a console or handheld. Wherever you fall, we assume that by visiting this site, you at least have some appreciation for the Nintendo DS.
Still, we're curious -- what was the first DS game that made you realize Nintendo's handheld was right for you? We're not asking about the first one you bought (although that may happen to be the same game), but what was the first title you played that really sold you on the DS?
