Yesterday I bought the Wii for my son including the game "Brawl". This game is some kind of an arena fighting game but with an additional story mode (arcade jump and run) and tons of cut-scenes, nice animated backgrounds and detailled characters (the heros from many Nintendo games appear in this one like Metal Gear Snake, Super Mario, etc.).

I found it quite interesting how good the graphics are in this particular game. You will find some great water shaders with ripples and real-time reflections. There is some kind of metallic normal mapping shader and there are tons of effects, animated skies and last but not least: nice looking soft shadows for the characters.
Did I mention the depth of fields effect and distortion shader?

The game also uses a good amount of polygons especially in cut-scenes. Everything runs fast and smooth, no fps issues.
