Size Matters

Ratchet & Clank: Size Matters

While this is still a very solid entry in the series, it's the lowest one in my opinion only because the PSP's control scheme is a little hard to do the job. That said, the developers still did a wonderful job and this game is not to be missed. If you only have a PS2, spend the extra to get this game. The controls are probably better anyway.

We got this game as a gift a few weeks ago and tried it. We played for two or three rounds (i.e. each of us read a question two or three times) and someone won. He got every question right the rest of us were one or two spaces behind him. Figuring we had just gotten some easy questions we reshuffled the deck and tried again. Only two rounds that time.
The questions are interesting and you do learn stuff you didn't know.
To top it off its not anything like I expected. We figured that it would be more like Dirty Minds, or a loaded question game but it's just a game of statistics.
It might be fun for children or teens but not for adults.

I thoroughly enjoyed this book. It feels like you're hanging out with an old friend on the back porch. It is a very easy read, and the topic is neat. I really enjoyed the part on quorum sensing, totally fascinating. Thanks for a great book! I went to the library and checked out 3 more by Dr. Bonner.

This game felt like the smallest of the PS2 R&Cs. Not as many worlds to explore before the final battle. By then you won't mind so much since you have been fighting against the camera as well as the enemies. If you like R&C and can get this game cheap, go ahead.
