I don't get when people criticize the Wii for having ugly graphics or defenders saying they care more about gameplay than graphics. People forget you can have beautiful graphics on Wii, it's all about art design.
Or rather it's about ideas and the tools to achieve them.
The Wii hardware is more than adequate for fleshing out any artistic idea you could have. It's just a matter of finetuning it for the tools you have at your disposal.
