The core gameplay most Def Jam Rapstar owners will experience isn't much different from what Singstar or Lips offers. It's the community aspects of Rapstar that could change the way the rap game is played.
At Gamescom today, we got our second demo of Def Jam Rapstar, with 4mm Games' Jamie King and Def Jam's James Waller battling it out with a bit of two-player in the game's party mode. Like Lips, Rapstar combines pitch detection portions with phoneme recognition, scoring players on both their abilities to sing in tune and rap on beat. We watched King and Waller go head to head in a few of Rapstar's confirmed tracks, including "Live Your Life" by T.I., "Gold Digger" by Kanye West and "They Reminisce Over You" by Pete Rock & C.L. Smooth.
