Due to the recent price drop, I am strongly considering getting a PS3. I am looking for a game that has some longevity, something that can hold my attention for more than a few months.
 
Little Big Planet really caught my attention a while back and the positive reviews it received when it came out made me think that this may be the game I should get. It seems like a game (providing that the community for it stays strong and that DLC continues to be released for it) that I could play for years.
 
However, I was wondering if, months after its release, there is a LBP community creating quality levels (as opposed to a stagnant community creating a lot of really crappy and mediocre ones)? Also, gameplay-wise, is the platforming more fun than it looks? From what I've seen it looks a little clunky.
 
I know what the reviews have said, but I just thought I'd pose these questions to actual gamers and, being a fan of Giantbomb, I figured this community would give me an informed answer.
 
(I also plan on getting MGS4 and GTA IV at some point in the future. I've heard, though, that the multiplayer in those games aren't as great as the single player campaign.)

Get Fallout 3 for longevity, I don't think Little Big Planet will hold your attention over a few months, even if you're super creative.

Yeah there are always some awesome levels being created, and you can usually pick from the top rated ones. The Platforming is good once you get a hang of it, sometimes it gets a little weird when trying to move between the layers, but besides that it's good.
 
No one really plays GTA4 online anymore, which is kind of a shame.
MGO which is Metal Gear Online (MGS4's multiplayer) still has a sstrong community, but is really for the hardcore crowd.

"I was wondering if, months after its release, there is a LBP community creating quality levels (as opposed to a stagnant community creating a lot of really crappy and mediocre ones)?"

If you really get into the creation side of things, then yes, it will hold you for a LONG time. Don't forget there is water being added to the game soon aswell, so that should lengthen things.
 
I still have a buddy on my PS3 friends list who has practically played LBP exclusively for the past year. There have been other games here and there -- but I'd hazard he's put in maybe 300 hours into that game.

The main game is very short. New Super Mario Bros DS short. 
 After that, decorating your pad is cool. 
Looking for cool online levels to play, there are some beautiful ones, but the background music gets annoying and it just became a boring hunt for nice levels to play in.
 soon lost it's charm to me. And I don't much fancy creating levels, I just want to play. 
However, I do recommend trying it once, it's a lovely game, just not for longevity in my opinion, unless you love to create and share.

I ended up getting the PS3 bundle that includes Little Big Planet: Game of The Year Edition and Ratchet and Clank: A Crack In Time at Best Buy on Black Friday for $299. I'm really enjoying playing online in LBP. I haven't made any of my own levels yet, though I'm looking forward to when I get the time (I'm currently playing through MGS4). Thanks for the advice guys, I really enjoy the game.
