5. 1 vs. 100
Why did it take so long for a game like this to arrive? An online interactive trivia game for a Xbox Live seems like such an obvious idea in retrospect. 1 vs. 100 has a similar setup to Who Wants to Be a Millionaire?, except the contestant (the 1) is competing against the Mob (the 100) and the Crowd (the audience). Everyone is eligible to win prizes that include Microsoft points and XBLA games. The network is surprisingly stable and the questions are pitched at a good difficulty. Those who enjoy playing along at home with Jeopardy! or Who Wants to Be a Millionaire? will love this game, it nails the game show feeling.
