I had the pleasure to participate in the beta for the very first LittleBigPlanet in 2008. It was my first Beta and was a great experience. Well now the boys over at Media Molecule are offering to you the same thing that was offered to me, the ability to participate in a LittleBgPlanet beta.
The LittleBigPlanet games are fairly unique in the sense that every game feature 4 player co-op and the ability to create your own levels from scratch. And people have, from completely working games of "Tetris," to people making costumes for their Sackboys. LittleBigPlanet for the Vita is the newest game in Sony's "Play, Create, Share" initiative that includes Mod Nation Racers and the upcoming LittleBigPlanet Karting.
All you have to do to sign up is go here, and enter in a little information about yourself such as your Playstation Network ID, your email address, and your date of birth. Then it asks you 3 questions. Which LittleBigPlanet games have you played before?, Do you own a PS VITA?, and Have you ever created and shared a level in any of the above mentioned LittleBigPlanet titles? Thats all, do that and you might get a beta code to help make the game!
