"Mario & Sonic at the Sochi 2014 Olympic Winter Games" marked a significant milestone as the first crossover sports/party video game for the Wii U console. Unveiled on May 17, 2013, this fourth installment in the Mario & Sonic series held the prestigious title of Official Video Game for the Sochi Olympic Winter Games 2014. Its release schedule was as follows: November 8, 2013, in Europe; November 9, 2013, in Australia; November 15, 2013, in North America; and December 5, 2013, in Japan.

This groundbreaking title introduced several notable features. It was the first in the series to offer an online multiplayer mode, expanding the gaming experience beyond local play. Moreover, it marked the debut of global publishing by Nintendo, whereas previous titles had been published by Sega outside of Japan.

In my capacity working alongside the SEGA Development Team and the Publishing Team at Nintendo, I played a crucial role in shaping the game's development. My responsibilities encompassed gameplay development and the meticulous approval of graphical elements, ensuring that each aspect of the game met the highest standards of quality and authenticity.

I take immense pride in my contribution to this title, as it represented not only the first HD installment in the Mario & Sonic series but also the inaugural Mario and Sonic game to feature online gameplay. This groundbreaking achievement stands as a testament to the innovation and collaboration that defined the project, leaving a lasting impact on the gaming landscape.
