Francois Poisson has been re-creating Ultima 3 using RPG Maker MZ (as much as is possible within the limitations of said game engine).

As of late July, 2024, the good Mr. Poisson has got “most of the programming part done”, and has also finished building the world maps for both Sosaria and Ambrosia, and has begun work on implementing specific regions and points of interest in the world (such as Lord British’s castle). He has also implemented a fair bit of the game’s plot, including the requirement to obtain the Mark of Kings before progressing into higher experience levels. Monsters and various NPCs have also been implemented.

The remake will probably not be released as a standalone application, and so will require RPG Maker MZ in order to run. No release date for Ultima: Exodus has been given as yet, but you can follow the Ultima Dragons group on Facebook if you want to stay informed about Mr. Poisson’s progress; he posts there on a roughly weekly basis. And if you’re not on Facebook, you can find a few screenshots from the project at the newly created project entry for it here at the Codex.
