Gameplayer has spent two days with LittleBigPlanet and its Senior Product Manager, Nick Robinson, gaining plenty of insight into what gamers can expect. It includes a look at why the game would not work on Xbox 360, and goes on to suggest that its success may force Microsoft's hand regarding their policy on user-generated content.

"We broached the subject of the Xbox 360 with Nick and whether LittleBigPlanet could function as desired on the format: the answer was a disappointed shake of the head. Echoing thoughts we heard from Epic Games Mark Rein last year regarding the issues they faced with wanting mods available for the Xbox 360 version of Unreal Tournament III (which subsequently resulted in a delay), and the frustration shown more recently by the developers of N+, Microsoft's Draconian – and frequently hypocritical (seems to be ok in Halo 3 and Forza 2) – restrictions on user-generated content is proving to the be Live's Achilles' Heel."

They sure have high hopes for LBP.

I'm on the fence about Little Big Planet (leaning towards buying it though) but I don't think it's going to do what a lot of people think it's going to do. I hope I'm proven wrong, though.

Im going to create a level that kills people instantaneously at the end...

I love the idea of other devs making LBP levels

I bet LBP is overhyped. Not a lot of people will spend more than 4 hours creating a level that could be done in 5 minutes. I don't get why everybody is so excited about this game. But I am looking forward to see how it sells.

 im gonna make a halo 3 level with stick grenades !!!! with sexy brute chicks !!! and and sexy flood creatures

I sure hope you are godsmack proven wrong.... :S

Isn't that the case of any user created content?

They're at least giving a way to sort through people's content and let everybody get a shot at playing the good levels.

^ The only difference this is going to be uder created content unlike anything seen on consoles and simple to create, giving it unlimited possibilities...
That's why everyone is so excited for this....

 Do you know what the Achilles Heel is?

It's not something that prevents you from being strong (like achilles) but it is something that will be your downfall. This is nothing wrong with what was said with the OP but so many things wrong in your post.
