Ahahaha, the unrestrained hate is a little over the top and unwarranted. LBP is gud; yes it had floaty jumps, but everything that made it great had mostly nothing to do with the "jumping" parts. It really comes down to this:
The real attraction of the game is the level editor. The game may look like it's evenly split between the level editor, the story mode, and the community made levels, but how much you'll like the last two depends on the first.
The story mode is more or less a giant tutorial mode meant to inspire the player with ideas for levels. If you're interested in creating stuff you'll find yourself trying to figure out how the design team created this or that contraption.
The online is definitely flooded with crap, but with "MM picks" and search filters like most played/hearted, this week/month/ever you're bound to find most of the good levels. But even that usually boils down to whether you're interested in the creation part or not because, much like the story mode, you won't appreciate 80% of the community content unless you do as the community is too focused on creating the most complex and intricate looking levels and contraptions.
There's a great deal of "play" in this game, but it definitely takes a backseat to the "create" part if we're making a fair comparison. Consider this: the story mode challenges you to collect all the giant bubbles in every level It's the most important collectible (other than score points) in the game, and what does those bubbles contain? objects, materials, tools for level creation.
In other words, it's not the bore's cup of tea, and probably not yours too Borys.
It's got some insanely creative (MM-developed) levels, and is quite playable unless you're some kind of dumbass, but it would have benefited quite a bit from some form of decent narrative. They banked entirely on whimsy and the whole make your own game stuff. Fun to play with the kid, but that's about it.
It's playable but it doesn't provide a challenge exactly with the platforming due to the floaty controls.
Yes, there's a great deal of jumping around, but story levels rarely focus on it to create the most of the challenges (I don't think anyone would like to see me spam this page with story level videos). See, if you played throughout the story you'd realize that, but you didn't.
P.S: most of these crabby geezers didn't too.
P.S.S: I'm playing the story mode right now in preparation for the second's release, since you can import your profile.
