Wii U

The Wii U, released by Nintendo in 2012, aimed to build upon the success of its predecessor. It introduced a tablet-like controller, the GamePad, which offered a second screen and innovative gameplay possibilities. The GamePad could be used to play games independently of the TV or as an additional display, enhancing multiplayer experiences.
While the Wii U showcased some impressive games like "Super Mario 3D World" and "The Legend of Zelda: Breath of the Wild," it struggled to gain widespread popularity. The console faced challenges with marketing and confusion over its identity, as many believed it was just an add-on for the original Wii. Nevertheless, the Wii U paved the way for the Nintendo Switch, which successfully incorporated the dual-screen concept into a portable console.
