This is my first Ratchet game and I mostly liked it. It's a fun and easy platformer with a lot of different mechanics, which try to entertain you in a various ways. Co-op here is really nice, there are a lot of things you need to do together (pressing buttons, focusing one enemy, shooting you friend to the distant platforms etc). I was slightly disappointed by the controls (weapon interface is terrible) and the length of the game, it should be quite shorter in my opinion. As for the rest it's a really nice game and I recommend to try it. I think this game should be especially good to play with your kids. Looking forward to play other games in this series.
