One of my most cherished YouTube videos is this strange 2007 number from a guy with 15 followers and the handle "FilmNoir82". It shows off a tech demo for an unreleased, post-apocalyptic RPG (with music ripped from David Lynch's 1984 Dune) by Troika Games, a beloved, but short lived studio founded by former Fallout developers Tim Cain, Leonard Boyarsky, and Jason Anderson.
The demo looks like an alternate interpretation of Fallout in full 3D, distinct from both Black Isle's "Van Buren" prototype of Fallout 3 and Bethesda's later vision of the setting. It appears as though you'd primarily play from an isometric perspective, but the demo also shows the player zooming into a first person view, possibly allowing for both immersive first person exploration and zoomed-out tactical combat.
