Iwata led the Wii to be the best selling home console of Nintendo, I would never call this guy a bad CEO because of this. Of course I'm not blinding myself to the most recent screw-ups, however I was always aware that Nintendo doesn't spin around Iwata. Wii U failed not because of Iwata's decisions but the development team decisions, they wanted to make a hardware with a power level they considered "neccessary" to execute their ideas in the form of games, they wanted the Game Pad to be Nintendo's most ambitious controller ever created. Wii U had bad sells because the launch games weren't convincing, the bad explanation about the Game Pad's concept made hard to develop something and the games with the best uses of the Game Pad (such as Wonderful 101, I love this game) ended flopping. Wii U had bad marketing because initially they tried to aim the hardcore gamer, but they forgot that these people consume powerhouses and defends traditional gameplay experiences (even with Nintendo offering the Pro Controller), after that, they tried to appeal to the former Wii audience but these mistook the Wii U as a Wii accessory. In the end, only Nintendo fans bought the Wii U and even them have complaints, myself included. I love my Wii U, have a bunch of games, but I know it's factually a flawed console because of its weird design decisions, and I assure you no one of these were made by Iwata, even with him being a former game developer.
