Awesome game design with fun open ended puzzles. Later on the puzzles do get a bit tricky and sometimes the game won't let you be as imaginative as you want to be with some items. I spent so much time just messing around in the sandbox on the title screen as a kid just spawning things, seeing what words worked, and messing around. The sequel, super scribblenauts, improves the formula in such a huge way that you might be better off playing that instead by now.
