I've been playing LittleBigPlanet since early yesterday, and I'm already willing to suggest that it is my favorite game of the year. That's above GTAIV, MGS4, Brawl, or anything else I've had the opportunity to play this year.
The online aspect of the game is currently not up, as GameStop released the game earlier than they were supposed to. So, for now, I've only played the "PLAY" and "CREATE" modes.
PLAY is incredibly robust and entertaining. They're stuffed with stickers, items, material, and bonus level keys. They've done an amazing job organizing the the content so that you can clearly see what you have left to do. If the game were this alone, I would be sold.
CREATE is just ridiculous. You're given all the tools they used to make the Story mode levels, so you can literally recreate an entire official level if you wanted. You use different unlockable material on your levels, so you'll need to spend a lot of time in the Story mode you make some really cool levels.
The game is also stuffed with tutorials on everything you need to know. You won't need to check out any Youtube videos to figure out how to put together any contraptions you may have in mind.
Overall, it's amazing. I'm pumped to see what the community has done with the tools as soon as it's up. On the two sections available to me alone, it's easily one of my favorite games. Disregard what people have said about other games before; LittleBigPlanet is the reason to buy a Playstation 3.
