I love my Nintendo 3DS and DSI. Both jailbroken and playing games on it versus emulating it has been a blast. And games are pretty unique because of the dual screen and stylus, so been the best console I've had by far.
This year I played through Hotel Dusk, Okamiden, and Trauma center on my DSI. And been playing through Super Mario 3D land with 3D effect. 3D effect from what I read works best on the last 3DS model since the eye tracking is better.
