I've gotta to say, I really enjoyed those PS3 Insomniac games listed. Resistance 2 was particularly impressive ( I got it with my ps3 bundle and it made me buy resistance: fall of man) - the graphics were stunning and then online play was inspiring (that said, I always come about 20th in a 120 player match =( )
I did play the Ratchet and Clank: Tools of Destruction and found it to be enjoyable but similar to the exsisting R&C Games. This said, I am very much looking forward to "A Crank in Time" as its trailers look 'mighty fine'.
