We all know the PS3 and 360 have way better graphics than the Wii. Yet I have seen several threads recently saying that Metroid Prime 3 looks considerably better than Halo 3, despite HD resolutions.
Artwork. I think Nintendo chose to put a less powerful graphics card in the Wii to force developers to spend more time on the artwork rather than resolutions and polygons. We've seen this in Zelda, SSBB, and Metroid Prime 3 and more to come with the upcoming shots of Mario Galaxy. This is why I think Nintendo chose to downgrade the graphics.
Which of these would you rather look at?
They aren't really that good of examples until you see them in motion. But i'd still rather see the artwork than the higher resolutions.
