And all those "otaku" games are on handhelds and sony systems. If this was really focus tested, they would've known that audience isn't on wii u.A game about high school magical idols doesn't seem a bit derivative and widespread in anime and Japanese games lately? The game is riffing on a bunch of recent trends.
It might not be WESTERN focus tested, but I somehow doubt there's just oodles of devs out there waiting to take their turn at involving teen idols in their games, yet somehow they keep cropping up a lot. Do you think all of the otaku bait games that have come out in the past 5 years or so have been done out of pure artistic intent?
But Atlus still chose this theme anyway.
