Short and simple. Unfortunately the deepness is not there for it to be truly replayable. This title is mainly for kids.
The game is a one player game, but a second controller can be used for each 'mission' to help control the search for Waldo and other special items. This feature is for parents to help their children to find the objects.
What would have been nice is a competitive mode for two players, a race against the clock to find Waldo. Understandably however, this game is focused towards kids, not 26 year old men who are ultra competitive.
The game goes through several stages, on one of two difficulties (though I can only imagine how easy the normal mode is - the expert mode was so very easy to play) where you scroll horizontally through a map to find Waldo and the Scroll while against the clock. You can often pick up clocks or other items to slow down time or pop up a quick search for a specific item on the map. Each stage can be done in less than a minute for an adult - if you have the skill.
There were only about 5 stages in the game, we beat the game in less than half an hour, with only one instance where my wife playing could not find Waldo (we all saw him, haha) The game's replayability is suspect - the only change to the game is the locations of where Waldo and the Scroll are placed. That is it.
Overall, this game is by no means for an adult or teenager, and may be used to show kids what they are missing out on if they can't get their hands on those wonderful books.
