Music creation:

the tools for world and sound creation in dreams look absolutely brilliant, quick and intuitive to use, yet have great results and super in depth configuration for ppl who wants that

I wonder what the game logic tools are like - I imagine those might still be quite a bit more intimidating

Gameplay is going to be everything you can imagine. It’s about user created content. The three campaigns only offer some inspiration.

I look forward to playing other peoples' brilliant creations (all of my creative talent lies in the written word, unfortunately. I could write a script for a creation, but that's about it). Given the PS4's position in the marketplace, I really do hope that this game can be just as big (pun intended) as MM's prior work.

For anyone interested, I put together a tutorial section on LBPCental many moons ago and it would be well worth taking a look. Logic will likely work with more complexity but it will definitely share the basics with LBP. Start with Comphermc

a innovative game, nice.

I was skeptical before because of how little we know. I also didn't love the art style before. I even commented that they should scratch their initial format. TBH I was proven wrong.
From what I have seen so far. I am very impress. The possibility you can do here. One of my must have now.
