Brain age... I'm sorry but someone else can make brain age, I'd rather get the next Zelda a year early. They're not in the same universe and I know which most would prefer. Brain age is a waste of Nintendos talent. Their talent demands AAA perfection. Indies can deliver the low budget casual stuff. Again MM wasnt buggy and Nintendo gave the devs 1 year to make it. In fact they put them under such pressure with 16-20 hour work days that many of the developers developed depression and health complications which made its way in to the game in the form of tonality, characters, dialogue. etc. It tried and tested and works.
You do realize that Majora's Mask only took a year to make because it heavily recycled every asset from OoT, all the way down to the interface. Besides, it was more of a fun challenge by the developers rather than a company wide mandate. MM was an anomaly in the Zelda series, and that can't be the rule for every game, not when AAA games are insanely expensive to develop these days. And whether you like Brain Age or not, letting Nintendo's developers make concepts like it is important. It gives them a chance to breath from the AAA stuff, while still encouraging hard work and creativity from them. A Nintendo under your leadership would be putting out less and less games because AAA titles are expensive and time consuming.
