Wearing my Agents of Doom shirt right now. 
Is Ratchet: CiT really that good? I'm in the mood for some platforming.
I wouldn't say it's
that goodBut it's a fun and pretty saturday morning cartoon game with good action & good (still easy, but at least very frequent now) platforming.
Some of the sidestuff is less stellar (plane shooting) but it takes all over 3 mins here and there and is easy and kind of fun in a super simple tempest but shallower way.
I guess the Clank stuff is give or take depending on if you like time/shadow puzzles like Braid. I enjoy them, so they add some variety between the shooting & jumping.
It's a nice looking game that is completely inoffensive yet fun and not too long, aka. saturday morning cartoon game!
I'm definitely enjoying it and feel surprisingly satisfied (didn't expect much after Resistance 2 and the first Ratchet PS3)
The Ratchet campaign is somewhere between Going Commando and Up Your Arsenal for me. The Clank puzzles don't measure up to Giant Clank, and the space combat is meh. The actual mini-planets you visit in space are cool, though. Mostly platforming there.
Plus the game has hover boots, which make the mini-planets oh so much better since you can blow through them really quickly.
