Mario & Sonic at the Rio 2016 Olympic Games will release on March 18 for the Nintendo 3DS, while the Wii U version of the party game has been reported as "delayed" by some media. During last night's Nintendo Direct showcase Nintendo took the time to talk a little more about this version of the game, which will be released on June 24. The game, just as the event itself, will feature golf as an event for the first time in Olympic history.
