The PSP has a great library of games that are not available on other platforms, offering a unique gaming experience. Additionally, the PSP can be a more affordable option for those looking to play classic games or try out new titles.

It depends on your personal preferences and gaming habits. The Wii U has a unique library of games that are not available on other platforms, such as Mario Kart 8, Super Mario 3D World, and The Legend of Zelda: Breath of the Wild. If you are a fan of Nintendo's first-party titles and enjoy local multiplayer gaming, the Wii U could still be worth buying in 2021. However, if you are primarily interested in third-party or more recent games, you may want to consider other gaming platforms. **

As of 2022, the Wii U is an outdated console with limited support from Nintendo and a small library of games.
