Some of the things that people criticized in the first LBP have been sorted and updated in LittleBigPlanet 2. For example, costumes can now be saved and shared so they are no longer locked to your personal closet of clothing. You can save and share them with the world. A massive amount of changes have been made to the creation side of the game including switch and wire updates, emitter changes, camera rotation and zoom levels and major additions to sounds and lights. There is of course the addition of the grappling hook, power gloves and new logic and other tools.
Now I’ve been working on my own LittleBigProject and even that is rather entertaining. Like all in-depth and robust creation tools it takes a while to get into it. There are some 52 tutorials that you can sit through if you like. Doing so gets you rewards after each one so it’s worth it. Plus, many of them are fairly entertaining thanks in part to the narrator, Stephen Fry. His voice is quite well suited to being the Hitchhiker’s Guide, I mean the narrator and he does truly good work.

Huh what? Oh right, yes, there’s a game in there somewhere. LBP 2, like it’s predecessor is all about fun and sharing. The sharing has obviously been massively expanded and the things that can be created with the game have been as well. But is the game itself fun? It is. There are loads of levels that you can simply play through and follow the story. You might even do that for hours and after that get into the community created levels and play for weeks and never even step foot into the creation area of the game. After all, not all of us are creative types and might not be interested in putting hour after hour of work into creating out own levels but might be interested in playing thousands of levels.
Many of the levels can be played in co-operative or competitive modes. There are things like races, points gathering and like I said, even racing. I haven’t gone too deep into the numerous community levels as I’ve been trying to take a balanced approach to the game’s three main points - story, creation and community. 
Overall, if you liked the first LittleBigPlanet you’ll love this one. If you’re creative you’ll find an avenue to express that creativity through for months to come. If you’re more of an explorer you’ve got 1.5 million levels to play and if you’re a collector, many level creators can give you rewards for downloading, playing and succeeding in their levels. So there’s all sorts of things that can be made and given away as awards and gifts. That means there’s a real reason to go an play dozens of other levels that were made by others. Plus, if the author is generous, you can copy their level layout and then edit or make variations of it. Once I’ve got my project complete I’ll be more than happy for others to play it, copy it and edit it.
