Rabbids: Adventure Party was announced for Switch a couple weeks ago, and as of right now, it was only announced for China. Lots of people want to see the game make it to their parts of the world, but as far as we know, there are no plans to make that happen.
In an interview with IGN Japan, a developer at Ubisoft Chengdu was asked about the game releasing in Japan. The developer gave one suggestion as to how fans could make that happen.
“If you are a fan who wants to see this game released in Japan, please send an email to Yves Guillemot (haha). It would really help if you do that!”
It's as simple as that! All we have to do is email Ybes Guillemot directly and request it! Now...what was his email address again?
