Apocalypse Road was the post-apocalyptic game Bethesda Game Studios had in mind before obtaining the Fallout license.
When BGS was working on Oblivion the team created a list of game settings they'd like to do, a post-apocalyptic game was at the top of it. Though they thought of Fallout at first, they didn't get the license until a year later. The name was settled on Apocalypse Road; Todd Howard had a logo made for the project, it was a road sign that said apocalypse with an RD. But all that was trashed once they obtained the rights to Fallout.
