The single-player portion of the game won't take more than an hour or two to work through. However, expect to spend a lot more time with it if you want to get gold trophies in all of the quizzes. The questions in
Buzz! Master Quiz can be so hard as to verge on feeling unfair. For example, one question shows a picture that has been blacked out save a small square that reveals a patch of blue and comes with the query: What kind of bluebird is this? Most people would have trouble identifying that it was a picture of a bird, much less the exact species. Even an ornithologist would likely be forced to guess the answer.
The multiplayer modes also feature some unreasonable questions, but they're a little easier to stomach, since the object isn't to try to get as many questions correct as you can but rather simply compete against others who are facing the same challenges. The most satisfying multiplayer mode is Game Sharing, which runs up to six players through a series of traditional first-to-buzz-in-style trivia questions, but it requires that each player have their own PSP. As a result, the most popular multiplayer game type will likely be Pass Around, which sees players answering single questions by themselves before passing the PSP off to the next player. Host mode, which has one person assuming hosting duties and reading off questions for everyone else, might be fun if you happen to have a ham in the group.
