Fellas... Dont you guys see the point?
This game is released for promotion of Nintendo's real products...
They WANT you to feel "something is missing" or "incomplete" so that you'd go out and buy Nintendo DS or whatever to fully enjoy it..
This is actually somewhat true. Nintendo will never ever make full games for mobile devices.
They want folks to buy into their systems, the Nintendo ecosystem just like Apple does.
However, the brains at Nintendo understand a child's first interaction with video games won't come from a controller. It will come from a smartphone.
So if they continue to make short, colorful and quick games with Mario,Zelda themes etc. they are hoping kids will then switch over to the big system at an early age.
