Based on the 50 games you've listed, I highly recommend the following five discs.

 

#	Game Title	Console	Critic Rating (Metascore)	Why It's a Top Choice for Wii U
1	Super Mario 3D World	Wii U	93 / 100	A must-own masterpiece and a technical showcase for the console. It offers fantastic co-op and uses the GamePad for interactive hidden blocks.
2	Metroid Prime 3: Corruption	Wii	90 / 100	This is the best way to experience the Wii's pointer control system. Playing it on the Wii U through HDMI provides a cleaner, sharper image than on the original Wii console.
3	The Legend of Zelda: Twilight Princess HD	Wii U	86 / 100	The definitive version of this classic. The GamePad makes inventory management and map viewing instantaneous, dramatically improving the flow of the game compared to the Wii original.
4	Assassin's Creed IV: Black Flag	Wii U	86 / 100	A phenomenal third-party open-world game that is well-optimized for the Wii U. The GamePad displays the world map and allows for seamless menu navigation, making sailing and exploration much more efficient.
5	Super Smash Bros. for Wii U	Wii U	92 / 100	The game boasts an 8-player mode, amazing visuals, and superior online features. It's the ultimate party/fighting game on the console, and it supports nearly every controller you have, including the preferred GameCube Controller (with the adapter).
