Avinash, why do you assume Nintendo only has the capacity to make a small amount of games, and can never increase that capacity? 2D Mario and 2D Metroid may be more diverisfied than 2D and 3D Mario, but both 2D and 3D of Mario and Metroid is more diversified and more profitable than either of those situations. There's no good reason they can't pump out a 2D Mario every year as well as making a 3D Mario every 3 years.
"Now, a fun game should always be easy to understand - you should be able to take one look at it and know what you have to do straight away. It should be so well constructed that you can tell at a glance what your goal is and, even if you don’t succeed, you’ll blame yourself rather than the game. Moreover, the people standing around watching the game have also got to be able to enjoy it." - Shiggy
