The Armchair Empire writes: "For the most part, I've missed out on the Ratchet & Clank series – always hearing good things, playing demos, watching some clips, etc. It always conveyed a sense of fun. But if I were to base my opinion of the entire Ratchet & Clank series on Size Matters, I'd be wondering why everyone lauds so much praise on the series. The camera is irritable and often does its own thing and the graphics are stark at the best of times; two problems that just don't jibe with a series that has always been about larger than life cartoon action."
- Hits most of the typical Ratchet & Clank conventions, like crazy weapons
- Action runs at a good clip
- The camera is an annoying mess
- Surely more can be squeezed out of the PS2 in the graphics department
