Do you need the move to play littlebigplanet 2?

Answer 1

It is a Move compatible game and that means it will with work with the Move Controller, but also with the Dual Shock 3 controllers. For LBP 2 since you need a navigation controller you can also use the left half of a Dual Shock 3 as your Navigational Controller (if you don't have a navigational controller) with the move controller or you can use just the the Dual Shock 3

Answer 2

No, you can play without PlayStation Move. However, you can do few extra things if you own a PlayStation Move.
