LocoRoco

Though Sony has promised that the best of LocoRoco has yet to be revealed - the preview stops short of introducing the dreadlocked Rasta Muji and the prospect of more active enemy avoidance - it's heartening to find a surprising amount of replay even in what little is there. The levels shown are tightly packed with numerous hidden objects and, with weight-determined switches and concealed passages, secret areas blocked off to all but the most protective and daring players.

In many ways, then, one of Sony's most forward thinking and progressive ideas is also its most backward looking, a rigidly simplistic concept drawn out in quivering jellied form, and with all its innocent charisma, seems poised to win over all ages.
