I wonder, is there a patch somewhere out there that enables the ending in fallout 1 in which the followers of the apocalypse survive? Or at least some kind of mod?
The Update Mod for Fallout 1 v1.1 perhaps. I haven't tried it so I don't know. At least it adds the people you need to help to get the good ending.
If that don't work you can get vad's fallout savegame editor and set "Gvar132:Train_followers" to 1 in your save game.
Not as much fun, but at least you will get the good ending.
