Project V13: the Lost SRPG by Black Isle Studios (Patreon)

Project V13 was the codename originally used for Interplay‘s original attempt at creating Fallout Online, an overly-ambitious MMO that was initially in development in 2006 by Engage Games Online, then by Micro Forté and in the end by Masthead Studios, before to be finally cancelled. The original Project V13 MMO was canned after a lengthy court case with Bethesda as Interplay lost the rights to make the MMO using the Fallout IP. Interplay could have probably tried to rework their MMO into an original IP, but we can assume they understood it would have been difficult to successfully develop and complete a quality MMO without enough money and without a recognized IP to work with. That’s when they decided to redesign their game as a classic isometric turn-based strategy RPG using a new setting, but still similar to the original two Fallout games: https://www.unseen64.net/2017/05/09/project-v13-srpg-black-isle-cancelled/
