Hvis man skal tro grundlæggeren af 5th Cell Jeremiah Slaczka, vil Wii U ikke have noget universelt Achievement/Trophy-system, hvilket må siges at være lidt af en overraskelse.
I stedet er det op til den individuelle udvikler at lave sit eget system, hvilket blandt andet også gælder Scribblenauts Unlimited:
"There are no Wii U accomplishments that are system wide. They are up to the developers to include or not include. Scribblenauts Unlimited loosely has them in the form of 'Global Starite Shards' which is like a giant checklist of global things to spawn and do in the game that aren't area specific,"
