The game is so much more full of life than its predecessor.  There's far more detail crammed into each screen, there's far more animation, and they now have NPCs with voice acting!  It feels like the first, only fine tuned and far more polished, with a wealth of new features to work with in Create mode.

Even things like the pop-it menu and tutorial prompts feel so much mroe well done.  It feels like they've had far more time and money to spend on all the little details with this game, which is great.

I have no doubt LittleBigPlanet will be taking home plenty game of the year awards yet again!

Also, Kotaku has put up some great impressions on the game, titled All They Did Was Add More Fun.

It seems that while the author respected the first game for the many things it made possible, he didn't really enjoy playing it, and as much as I hate to say it, he is certainly not alone in his feelings.  However, the sequel has changed his view entirely:

But I confess that I admired the first LittleBigPlanet more than I hankered to play through it. The game looked great, but, as a side-scroller, it had to compete with my favorite Mario games. It had to vie with my memories of the best Kirby and Castlevanias, the old Metroids and rest of the wonderful two-dimensional games I've enjoyed for years. LBP 1's levels were must-see, but, good as some were, they didn't feel like must-play.

As I played LBP 2 this morning, my feelings were transformed. The game's creators at Media Molecule have added great gadgets — a Bionic Commando-style grappling hook and a cake gun that shoots cakes that stick. There may be more. That's all I've wielded so far. The new items make moving through the game's developer-created levels more fun. Thanks to the developers' smart positioning of grappling points and trampoline-like jump pads, they make moving through the levels more rapid. I didn't hop through LittleBigPlanet 2's levels. I twirled through them. I still don't love the floaty jumping in the LBP games, but the jump pads offer a more spiked leap; the other items make jumping a less common means to get to the end.

There are some 40 levels in LittleBigPlanet 2's campaign, with the expectation that gamers will add thousands and thousands more through the game's online-networked creator community. I tried pieces of maybe a quarter of the first 40 and I was having a lot of fun. My old experience was that I played LBP with the desire to quit out of each level and hurriedly see what other levels had been created and uploaded. This morning, I wanted to keep playing what was there.

can't wait!

Great, now sackboys grand adventure has been spoiled.

why is the video not loading for me??? I really want to watch this >_<

I played the demo Sackboy's Prehistoric Moves that use LBP2 engine with support to PS Move... and the game is fantastic playing with Move.

One person controls the Sackboy and other the Move cursor for team work.

I and my friend love it... so much fun.
