The Wii U Library
The Wii U was released in November of 2012 and has already built a robust library of games in its first year. Iconic Nintendo properties such as the Mario and Legend of Zelda series have already seen multiple releases. The system boasts 216 retail releases at present, and many more titles are available through Nintendo's Wii Ware and Virtual Console download services. It is also backward compatible with the original Wii's game discs.
Nintendo's In-House Development
Nintendo's first-party lineup for the system features many updated sequels to their classic properties. Game & Wario is a fusion of Nintendo's Game & Watch and Wario Ware microgame series. New Super Mario Bros. U and New Super Luigi Urevive the classic 2D-platform style of the original Mario Brothers games, The Legend of Zelda: The Wind Waker HD revamps, the classic Gamecube game and makes a number of improvements that players have been hoping for.
Many Nintendo properties are also scheduled for upcoming release in late 2013 and early 2014:
Donkey Kong Country: Tropical Freeze
Mario & Sonic at the Sochi 2014 Olympic Winter Games
Mario Kart 8
Super Smash Bros. for Wii U
An as-of-yet untitled new Zelda game is scheduled for a 2016 release.
Aside from Nintendo's own in-house properties, exclusive releases currently on shelves include Rabbids Land, Lego City Undercover, Rapala Pro Bass Fishing, Sonic Lost World and ZombiU.
There are also a few intriguing third-party exclusives slated for late 2013 and through 2014: Capcom's stylish action game Bayonetta 2, Nintendo and Atlus crossover game Shin Megami Tensei X Fire Emblem, and the hotly anticipated RPG X from Monolith Soft, sequel to the Wii's smash hit Xenoblade Chronicles.
One of the original Wii's biggest selling points was its revival of the "exercise games" genre, and the new system continues that trend. The Wii Fit U and Fit Meter allow players to chart activity, create exercise routines and compete with other players online. The Wii Balance Board is the primary peripheral used for Wii workouts.
These peripherals include workout games of their own, but two separate retail releases are also currently available that feature workout routines: Zumba Fitness World Party and Your Shape: Fitness Evolved 2013.
The Wii U's Future
While the system cannot compete in terms of horsepower with the upcoming Xbox One and Playstation 4, Nintendo has the advantage of an extra year of development and retail releases. Access to Nintendo's deep back catalog (by way of Wii backwards compatibility and the Virtual Console) is also a strong selling point for the console. Nintendo also has a unique cross-market appeal to both longtime hobbyist gamers and the emerging "casual" market, whereas Sony and Microsoft tend to focus on the "core gamer" that spends a lot of money on new hardware and AAA releases. It's uncertain whether Nintendo will be the market leader in this new generation of consoles, but they almost certainly will enjoy comfortable sales and a sizable user base.
