NINTENDO DS
The original Nintendo DS, featuring two screens, was likely one of the first gaming handhelds I ever played on. The games I remember playing the most were Pokemon Platinum, Pokemon Soulsilver, Animal Crossing: Wild World, Mario Kart DS, and New Super Mario Bros. I've been told stories of myself when I was around six years old, and me telling my uncle he was "not smart enough" to try playing on it. Nintendo as a company is also the first I was exposed to, and I have been a fan ever since I started playing games on the DS.
