EDIT: Now in High Quality! http://gamescom.gamespot.com/video/6273814/ (disregard the other 3, this is the one to watch)
Here's a few gameplay videos, snatched from GameTrailers =D
Part 1: http://www.gametrailers.com/video/gc-10-ratchet-and/703071
Part 2: http://www.gametrailers.com/video/gc-10-ratchet-and/703072
Part 3: http://www.gametrailers.com/video/gc-10-ratchet-and/703073
I'm still busy watching them but so far… it looks FUN!
hey I like what I see so far =D now I definitely want that game 
I just finished watching them and they look sooo damn fun I can't wait to play it with family and friends XD
Awesome gameplay!!! I like that second one (swinshot part)
I just noticed that Gamespot has a video too… (you can download it)

But it's pretty much the same as the first 3, but with better audio so you can hear the voices, sounds and music 
I;m still laughing at Qwark's entrees and the Epic fail with Ratchet Qwark and Dr. Neferious trying to cross that bridge.
Lolz yeah, I laughed at that too. Can't wait to do some silly stuff when I play it with the family 
Nefarious cracked me up in that Gameplay video too!
I saw this video too and MAN IS LOOKS SOOO COOL AND FUN 
especially when you can annoy the other players by throwing them off the cliffs and all that 
too bad we have to wait a long time for its release!
I love that gameplay video, makes it harder for us to all wait another year until it releases 
Yeap, it's a bit hard having to wait a whole year… but at least there's still stuff coming for R&C this year 
well, we especially need to know what happens in the comic to know the games plot better anyway XD
