There is a lot to consider. First, quality aways take time. GTA still need 5 years to get done, even witht eh amount of people they could hire. What nintendo realized so long ago is that 9 woman can't give birth to a baby in one month. EA and Activision are starting to realize this now, giving more time to the studios to work on their games, Ubisoft still don't see this and this like unity happens.
And there is too the nintendo style. Nintendo aways tries to guarantee that games they publish has a minimum of quality, and for this to work, they can't hire upper managment people without garanting that they understand what every nintendo game need to have, where to work and where to polish.
If nintendo is to expand, i really think that thoose new teams should work on their own new property, like monolith soft did.
Before talking about the litlle amount that nintendo puts out out of their catalogue of IP, take a cold and deep look at sega. How many IPs of theirs are still alive? When sony and microsft had a as big catalogue of the ips taht nitendo have, then you go and tell me how bad nintendo "underuse" their IPs now.
"Hardware design isn’t about making the most powerful thing you can.
Today most hardware design is left to other companies, but when you make hardware without taking into account the needs of the eventual software developers, you end up with bloated hardware full of pointless excess. From the outset one must consider design from both a hardware and software perspective."
