Nintendo gave us the analog stick, the "dance pad controller" (even though it wasn't for dancing at the time), voice control (there was a mike in the Famicom controller), and saved the entire industry when it was on the verge of collapse in the 80's. They've made plenty of good decisions. They've made some bad ones, too, of course. That's because they take risks. The Game Cube's "kiddy image" shouldn't matter, since image is pointless. All about the games, and GCN has enough "adult" games. I don't know what they were thinking with the cartridges, though...
