Wii U early adopters will have 23 games to choose from when Nintendo's new console launches on November 18, 2012. The two marquee first-party titles are New Super Mario Bros. U and Nintendo Land, though the console maker is also listed in the press release as the publisher on Ninja Gaiden 3: Razor's Edge and SiNG PARTY.
Nintendo's Wii U launch window covers a nearly five-month stretch of time, from the day the console is released to March 31, 2013. A total of 52 games are listed for release during that time, with some planned for as soon as late-November. Highly anticipated first-party games that aren't arriving on launch day, including Game & Wario, LEGO City: Undercover, The Wonderful 101, and Pikmin 3, are unfortunately just listed as "launch window" for now.
Check out the full list, broken down by publisher, in the original press release.
