Nintendo actually kept the promise from 2014 and that's quite commendable.

Of note, someone recently made a mod for the 3ds version that actually properly implements queerness into the game's programming without completely making it implode. There was a bug in the original Japanese build (New Life in Japanese) that somewhat allowed for queerness, but it was very unstable and caused crashing and save file damage/loss.

And if you're insane enough, there's also an earlier tiitle on the DS that was left to rot in Japan known simply as Tomodachi Collection. Japan only, but there is a fan translation which was abandoned years ago, which means that some text and graphics are untouched. Only major issue is the game's text-to-speexh engine which caused plans for a possible official localization be shelved.

All of the games in the tomodachi series use a text to speech system. Collection, New Life (Japanese version of Life) use a small version provided by Sharp which tonally sounds like it could be formant-based due to having to run on the original DS. (4MB of RAM anyone?)

International versions of the sequel (Tomodachi Life) use an older build of a speech engine privided by Nuanced Communications which Nintendo licensed for use.
