alright so I am waiting your word on if this is good or not, I sold my PS3 to get just a normal Bluray player, but I miss my ps3 for this game, and killzone 2 and a couple others, I have the Metal Gear Solid Pack coming to me this week, I am interested in seeing what you have to say! let me know.
It might depend on your tastes and if you're a platformer kind of person. I've only played for a few hours in single player and 2-player offline, and so far it's delivering on all the pre-press hype and reviews. It's cumulative score on metacritic.com is 96, which is very high:

As someone whose only been gaming for a year (today's my one year anniversary of buying a PS3 ), it's easy enough for me to play, but still poses plenty of challenge (I'm not yet able to find and access all the treasures on even the first few levels). The Story Mode can be likened to LEGO Star Wars, in which you do a lot of exploring, searching, and problem solving in order find and acquire all the hidden goodies, which then serve you in the design of your own levels (something the Star Wars game of course lacks). Unlike Star Wars, there's no gun play or flying around in space ships, though using the jet packs is really cool.
My girlfriend (who doesn't play many games) joined me in two player mode last night and thought it was a hoot. She especially liked customizing her own character.
It's definitely on the cutsy side, like playing around in a PBS children's program. But if the thought of using your creativity to design your own levels and share them with friends and the PSN really interests you, and platforming with thoroughly customizable characters through a wide variety of environments, then this game is a must have.
