Yeah, as he was going off I didn't even have a clue. Dude was a genius.
Games like Nintendogs and Brain Age especially. Those two games not only showed off how incredible the DS' dual screens and touch screen were but they were so different at the time. Casuals and hardcore lapped it up.
Iwata definitely thought out of the box. I'm going to miss him when NX launches. There is still a lot of creative talent at Nintendo but still.
