Def Jam Rapstar

Def Jam Rapstar is a rap-themed karaoke game. There are two modes, Career and Party modes. The Career mode is in five stages. Each stage has eight tracks for the player to master, including a New Song Challenge which is unlocked as the player progresses through the stage. The Party mode allows players to simply pick an individual song and perform it.

Executive Vice President Paul Coyne of 4mm Games said, "Internally, we used [Get on da Mic] as the architectural model of how not to do Def Jam Rapstar."

In using censored radio versions of every song in its setlist, Rapstar becomes the first Def Jam game to be rated Teen by the ESRB since Def Jam Vendetta. Players are also not obligated to sing profanities, and missing any does not affect their score.

The PlayStation 3 version received "generally favorable reviews", while the Xbox 360 and Wii versions received "mixed or average reviews" according to video game review aggregator Metacritic.

The Guardian gave the Xbox 360 version four stars out of five and called it "an absolute must. If you've found yourself mouthing the words to A Milli on the tube, there's a huge amount of fun to be had here. And while it doesn't have the universal appeal of its more mainstream counterparts, the potential of its online feature means it could well become a huge sleeper success."
