Um Jammer Lammy is the wonderful sequel to Parappa the Rapper. One of the coolest things about it is that you can play the entire game again as Parappa with different music -- special Rap versions of the songs! Plus, you can play the game two player. I'm sure there's other hidden stuff as well. The main musical feel is rock 'n roll, as opposed to hip hop and rap, so musically most people will have a much easier time getting into the songs.

On the third day, I aced the airplane stage with Lammy, getting Cool immediately and holding it throughout the entire stage, racking up over 3000 points. People were cheering at the end and looking shocked, including the Sony people manning the game. I guess after having tons of people fail to complete the first stage, they were pretty surprised. One guy said "It's an honor to meet you, man" -- ok, ok, I admit I did well but he was taking this WAY too seriously. ^_^
