'Kameo' carries the lofty legacy of being a Rare game - it is a creation of the team behind such classics as Goldeneye on the Nintendo 64 and Banjo Kazooie. However, Kameo fails to fill the immense shoes it must wear simply for being progeny of the aforementioned dev team; despite this, it manages some light, simple frivolity, that is clearly aimed at the younger crowd. If you're in the market for a family-friendly game, this and Viva Pinata immediately spring to mind.
The storyline is all fairies and trolls, and won't interest the player beyond novel intrigue. The protagonist's evil sister, Kalus (how clever) is envious of Kameo's form-transmuting abilities; seeking vengeance, she liberates the Troll King, captures Kameo's family, and scatters the 'elemental warriors' (the different forms the player can assume) across the land. You can pretty much infer that all this will need rectifying quick-smart, though personally I don't care about her annoying relatives.
Kameo is a cross between a platformer with extremely light puzzle elements, and a beat-'em-up; you'll spend half your time using various elemental warriors to tackle obstacles (such as ascending icy slopes, rolling up ramps to get across gaps etc.) and battling a hodgepodge of beasts and creatures. Different enemies will require different approaches (but not to the point that I would deem it 'strategic'), but once you know how to annihilate the hordes of colorful morons that assault you, its simply a matter of doing it again many, many times. Bosses often require increasingly frustrating tasks to be completed in order to fell them. The game is simplistic, sorta fun to a degree, but fails on many levels to excite.
The visuals, however, are impressive. Kameo is a first-generation 360 game, one of the launch titles intended to showcase not only the new kid-friendly range of games, but also the console itself. The game achieves this with a style akin to animated films, a vibrant palette, varied environments, and throwing dozens of the manifold agents of darkness into the fray at the same time. Audio-wise, nothing really stood out for me - though the sound effects were capable enough, just not fantastic.
