It's not all that bad
With that said, graphically it is fine, at some points - in my opinion - it didn't stand up to the retail version that is n the PS3.
However it's colorful environments, nice platforming sections, and it's very funny and very clean humor make it a great game for the young and young at heart.
It's good to see that not every game has to be real and gritty. sure Ratchet and Clank keeps the third person shooter scheme, but your using laser whips, and guiding tornado's with your sixaxis. the wacky and zany weapons never seem to get too old.
for $15.00 - $10.00 it's not all that bad, considering a $10 dollar DVD may last you no longer then 2-3 hours max, it took me just about 4-5 hours to complete from start to finish. Also if you like a bit of good humor and something good for the young ones, this is a sure good buy.
