i feel this was an Insomniac's answer to Sony requesting them to make a downloadable version of Ratchet and Clank.

The game was cheap and short. I feel that since it was a game that you downloaded is the reason for it being so short. The game took about 4 hours to download and I beat it in a hour and half. Overall the game was similar to Tools of Destruction in every way including guns and enemies. The addition of use of Ratchets wrench was ingenious and a nice improvement. Also the water graphics were greatly improved. Overall the game was interesting and a great use of Sony's game downloads, but I could of waited for a fuller longer game release which at the end of the game they mentioned will be in Fall of 2009. I wonder why they even bothered creating this game and it was probably to make money off Ratchet and Clank super fans, which I fell for.

I would say if your a Ratchet and Clank fan who has to own and play every game Insomniac creates then buy it play it and enjoy it for the short time that you will play it, but don't expect to get a great lengthy Ratchet game.
