Jens Alfke has a hilarious review of Zack and Wiki:
I’ll say it up front: ZackAndWiki: QuestForBarbarosTreasure is a disappointment when measured against the expected checklist of wiki features. Most seriously, it has no text editing at all, either WYSIWYG or markup. Instead the “pages” take the unusual form of 2 1/2-D environments, like jungles or ice palaces, that you “edit” by pointing to and manipulating “items”. This is a lot more limited, but in compensation the overall interface is extremely polished, with lots of colors and animation. Editing is accomplished by moving the Wii remote in a variety of intuitive ways, and offers nearly the expressive power of a keyboard while looking a lot cooler to do.
There is more. Go read it. Side-splitting for wiki geeks.
