Wii Menu (Nintendo Wii)
Wii Menu is a graphical shell that is a part of Wii's system software. The menu is divided into four pages, each one with a 4:3 grid and each displaying the current time and date. There are applications on this menu known as "Channels" that you could interact with (Mii channel is popular example) can be navigated using Wiimote's pointer capability.
Wii Console is one of most best-selling consoles ever in video game history and it even brought impact on gaming industry by it's motion gimmick that revolutionized it. Also the Wii Menu is one of iconic console menus that deserve a representation in Console Wars.
As for layout, it would be walk-off stage that takes place inside a Wii menu. The foreground of the stage would be based on Mii channel's floor pattern:
The "channels" would appear in background like Mii Channel, Wii Shop channel and even virtual console that shows games ranging from NES classics to N64 ones.
The Miis and cursor make cameos in background, cheering up players during the battle.
I nominate Wii menu, because it represents Wii console, one of consoles that changed the whole gaming industry by it's motion gimmick that I mentioned earlier. Speaking of Wii, this console introduced Miis, the avatars that you could customize whatever you want and because of their popularity, the Mii maker was ported to 3DS, Wii U and Switch.
