For years a group of developers has been working hard on making an unofficial sequel to Mother 3 called Mother 4. But after a wave of DMCA takedowns from Nintendo, the team went underground but resurfaced recently after rebranding its project as Oddity.
Although Oddity is no longer the unofficial Mother 3 sequel, it’s still influenced by the series. A new trailer shows gameplay that’s quite similar to the original Game Boy Advance Mother 3 gameplay. But technical flourishes and graphical improvements also show that this is a modern video game production. You can watch the trailer here.
