LBP may not be the casual-core bridge sony wants it to be.

while you do bring up some valid points you miss the grander scale of things. LBP's level creater is the Hardcore side of the game. The levels being the Casual side.
Casual players want something quick and easy to play. Hardcore Gamers want sophistication and to never get bored with a game, customization will keep them occupied.

You make it sound as if LBP won't have any standard levels already on the disc or something. The game will come with over 50 levels to tread through from the start. Then once the casual player has finished that he/she can download free new levels to go through from more experienced players off line. This will then get the Casual players pumped, and make them want to try it out for themselves. This in turn leads to Casual Gamers becoming Hardcore Gamers.
