The Wii with its underpowered graphical prowess has already provided gamers with some of the best looking games of this generation. How is this possible, one might ask? Simple, outstanding art direction. We have seen games like Super Mario Galaxy, Okami, No More Heroes, Zack & Wiki, de Blob, and the upcoming Madworld. Every one of these games oozes with style and has a very distinctive artistic style that allows its lackluster graphics to outshine the pixel-pushers of some of the other systems.
Of course this isn't anything new, but only now has it become clearly apparent with the Wii and DS being significantly underpowered when stacked against their rival machines. Not only will the stylistic presentation of games with great art direction outshine most "realistic" games, but they will likely stand the test of time as well. As technology pushes forward, these games will simply be seen as relics of the past, artifacts of a time when technology was only capable of doing so much.
I think the perfect example of this can be seen when looking at Wind Waker and Twilight Princess. Granted Twilight Princess still looks great, but Wind Waker is literally breathtaking and its stylistic approach to the series will always be remembered and revered.
I can only hope that more game designers start to see this simple fact and adjust their goals to achieve great art rather than great graphics. While this approach shouldn't and won't work for everyone, it would be nice to see a longer list of companies who take the stylistic approach rather than the realistic one.
