The song selection is decent, plus you can download additional tunes (Xbox 360 and PlayStation 3 version only), which show up as a different color, plus this sequel is the first in the series that lets you play in a new co-op head-to-head mode (Xbox 360 and PlayStation 3 version only). In the Xbox 360 version you can also connect you Xbox Vision Camera to import your face into the game.
But these online options raise the first issue in this game: a headset microphone is required to chat with people you're playing with over the Internet even though you're holding a microphone in your hand. Does that make sense? Another beef is despite some new songs and a few new venues (including the finals stage from the 2008 season of American Idol), all the menus screens, graphical presentation, and the stiffly animated characters (which you can customize to look like you) are virtually the same as the previous game, which will likely disappoint those who purchased previous games. This disc isn't horrible – singing with or against friends to familiar songs and being critiqued by the American Idol judges can be quite fun – but this game offers little improvement over the past titles, making this sequel feel rushed and half-baked. Note: the Wii version is missing some of the more interesting features found in other versions that contribute to its replayability.
