As of today, the Nintendo Seminar 2015 titles have been released in Japan. Unlike last year which had the total seminars released in one package, these titles were released individually.
For the uninitiated, the challenge was issued to University Students either within the Tokyo or Kansai regions of Japan, allowing them to make games in the Unity engine that utilized the Wii U GamePad. The games accepted are part of the Nintendo Seminar.
Check out the teaser videos below!
Thanks for the tip, Daan.
