Wii U won’t make Achievements Mandatory for all games.

It'd probably be for clearing each chapter plus clearing them without messing up. Same with Professor Layton, except you get an achievement for solving a certain amount of puzzles too.

Sorry, but I knew someone would say that... of finishing the game in a certain amout of time.

That would suck for the game... as no sane mind replays it, knowing how it solves itself. Really awful... achievements used to make the game worse, as no one plays it thinking of "messing up"
