Eurogamer: "In graphical terms, next-gen consoles have matured to a point where developers are really pushing at the edges of platform capability. It's an arena in which the Wii, with its sub-HD capabilities, was never designed to compete.
It's far from obsolete, though. Sonic Colours is a reminder that visual impact needn't be about bump-mapping and high dynamic-range lighting. One level, aptly named Starlight Carnival, is a textbook example of how to get the most out of a less well-endowed machine."
