i guess if i had to say what i would like from nintendo on mobile...
maybe if they had created a brand new episode of animal crossing for mobile, complete with A.I. neighbors and everything that i know and love from the doubutsu no mori series... that would have been more satisfying for me than miitomo. but i realize the chance of that ever happening is very slim, considering the enormous amount of work that is required for writing and localizing all of the dialogue for a game like animal crossing.
however, for the most part, i really don't know what i like in a new videogame until i see it. i would much rather leave it to the creative people who make the games to surprise me with something new. show me something that i didn't know i wanted -- that's the best. very often, i find that the worst kind of art/music/movie/game is the kind that seems to be created by second-guessing what the fans want, or outright asking the fans what they want. good art is not created by committee, it's created by an artist (or a team leader) who has a strong and confident vision of how the thing should be. if they're worrying about whether or not i am going to like it, then it's probably doomed to suck.
