I get disgusted every time I read the changes.
It's nothing more than polishing up the graphics, some minor improvements and Miiverse integration... There are no new dungeons, no new content, nothing new to justify it as a "new" game.
Don't get me wrong, I love polished versions... One of my favorite games of all time is P4G, but even that adds new content... New dungeons, characters, endings, Personas, social links, locations, and additional gameplay time. And other HD remakes like MGS or Jak... They bundle their games together and charge a significant reduction from the price of a regular game.
But Nintendo, all they're producing is the same game with a little polish then charging full price for it. And the worst part is that they're getting away with it.
