We didn't have Mario & Sonic at the Pyeongchang 2018 Olympic Winter Games (wow, that is a long name), and that can mean one of two things: SEGA is either taking their time to develop a really good Tokyo 2020 game or they just gave up on the concept for good.
Mario & Sonic is my guilty pleasure franchise, and I'd love to have it on the Switch. And since the Olympic Games will take place in Japan, there's no better time for Nintendo and SEGA to partner up. What do you think?
