Although the wood-grain Atari 2600 was also my first thought upon reading the title, I think the Wii’s minimal footprint is impressive considering that—in the case of the original model—it’s also a GameCube.

Wii Mini, Wii, and Wii U

In contrast to the Wii’s 2006 release, the Wii Mini is arguably not yet ‘retro’ with its 2012 release, but definitely looks a lot sleeker, albeit not worth the loss of GameCube functionality for its minimal size savings.

Compared to both, the Wii U is super bulky, and lacks much use beyond improved emulation capabilities now that nearly all of its exclusives have been re-released for the Switch.
