Scribblenauts has a lot of hype to live up to; even the box tells you that you can "Write anything, solve everything" in this puzzle game. You can't write literally anything, but you can certainly come close and the result is one of the most creative games I've ever seen, the result of collaboration between WB and 5th Cell. Depending on who you ask, Scribblenauts is either an amazing sandbox to play in, or a collection of interesting puzzles. Its major game mechanic is its roughly 20,000 word (by the last counts I have heard, at least) dictionary; if it's in that large group of words, you can summon it onto the stage and try to use it to solve the task at hand. All you have to do is write it or type it into the on-screen keyboard and it will appear.
