Having played a fair amount of Child of Light I can confirm a few things: the writing isn't great, the systems are surprisingly in-depth and above all, it is drop dead gorgeous. The word I like to use to describe it is 'handsome'. It is a goddamn handsome video game.
The above trailer for Child of Light, I think, is rather unique. It reminds me of the amazing Prince of Persia trailer from a few years back, the one with the Sigur Ros song as background music. That trailer managed to make its world seem gloriously gorgeous, but used actual game footage to do so. This Child of Light trailer pulls off the same trick: it manages to use game footage, but also feel remarkably stylised at the same time.
Its a trick that can only be done successfully with truly gorgeous video games. Prince of Persia was gorgeous and Child of Light is also gorgeous.
Not, not gorgeous. Handsome. That's a much better word. Much more accurate.
