You can't give an answer really but I'll try. Littlebigplanet is basically the perfect game. Someone made a platformer but what if you don't like platformers? play a shooting level. Someone made a puzzle level but you can't do puzzles? play a racing level. What I'm trying to say is that there is something for everyone on littlebigplanet and if there isn't anything for you there yet you can easily make your perfect level yourself. If you don't like it still because of the effort you might have to put in, you can wait for the second littlebigplanet which isn't that far away now.
