Wii U still has no official in-game reward system like PS3 Trophies or Xbox Achievements according to one third party developer. 5th Cell co-founder and Creative Director Jeremiah Slaczka stated in a thread on NeoGaf “it is up to the developer to include [achievements] or not” in their own games.
He explained upcoming Wii U 5th Cell launch title, Scribblenauts Unlimited, contains in-game ‘Global Starite Shards’ which are “like a giant checklist of global things to spawn and do in the game that aren't area specific.”
Jeremiah went on to state “things could change in the future…I’m sure Nintendo will do plenty of updates and new integration of systems as time goes on.”
