The game looks good, graphically and gameplay wise.
Playstation branded games have always had a wide variety genres. If youtube and myspace are any indication, there are ton of people who like to share what they do, so I'm assuming there will be a large audience for this game as well.
And for those who say "Where's the story?" Well, there are such things as creative people in this world who like to make things for people and not just take what is handed to them, like how the game industry has acted for the last twenty or so years.
