Would it really be everyone's fault though?SMG2 is it's own story. It's basically DLC that had too much content to be DLC so it became it's own game. In the same way the later Super Luigi U did.
Skyward Sword is Miyamoto and Aonuma's fault. The reason is simple. Two words.
Collective responsibility.
If you oversee a project this large, the whole team takes the blame is things go wrong. It's no good just passing the buck back and forth between the team. The buck has to stop somewhere and it does, with the entire team. If SS failed anywhere, it's the whole SS team's fault it failed. No one individually, just the entire tram as a whole. Of cause the entire teeam takes credit for things done well too.
Let's picture this for a second. SS was being developed for 2 and a half years. You are designing the game to not use motion controls. Then, Miyamoto forces you to altogether scrap every single thing you work on to use the Wii Motion Plus. After some testing, you find that the technology just doesn't work. So after about a 3 months of testing, you shrug it off and go back to what you were previously working on. Then Miyamoto comes back and absolutely forces you to use technology that doesn't work. You have to scrap all of your designs, redo all animations, completely remake all enemies and create an entirely new AI system. So the team was forced to start completely from scratch after 2 years of development. Then you have to completely switch gears, work with technology that doesn't work to make it somewhat work, completely remake all AI and make everything designed for this system. On a system that doesn't work. Not only that, but you have a strict deadline despite all these setbacks, because you need to push out this game before the Wii U arrives.
Regarding all of these circumstances. The development team did a great job for what they had to do. But no. The team merely did the best they could with what they had. It was Miyamoto's fault for completely flipping the table on it.
