LBP2 looks amazing. I could play with the god damn synthesizer for hours. Let alone all of the other new stuff added. And it's getting a nice graphics and optimization boost if I heard correctly. Should be an awesome game, the only way I can see getting bored of something like it would be to really suck at create mode. Even then you have a virtually limitless amount of levels to play on.
LBP2 will make creating so much easier, and double your capabilities at the same time. Game is love I tell you, love.
