This thread will track Nintendo's first-party releases across 2017 to 2019, primarily on Switch, but will include information on 3DS games, as well as mobile games developed by EPD or other subsidiaries. 'First-party' in this context is going to mean games developed, licensed or funded by Nintendo - not games that are just published by Nintendo, i.e. Octopath Traveler is Nintendo-published, but it doesn't tell us anything about how Nintendo are allocating development resources and it doesn't use a Nintendo IP. That's one purpose of this thread - to see which studios have released or are making games, or which have no known projects underway.
This post will include Nintendo's internal studios - Entertainment, Planning and Development (EPD), studios owned by Nintendo (subsidiaries), and studios that have specific deals with Nintendo and are usually Nintendo-only (affiliated). The next post will contain third-party studios working on Nintendo-licensed or published games, i.e. Ubisoft Milan & Paris, Mario + Rabbids, as well as studios who've worked on remasters for Nintendo and might do again in the next 18 months or so (Tantalus, Monster Games). Studios who work on mobile games or network services might also be added to the second post.
Games without an official reveal or announcement will not be listed (e.g. no rumoured Star Fox, no unofficially confirmed Pikmin 4).
Games listed are for Switch unless otherwise stated.
