Fallout to me means thought provoking storylines on the nature of man and government post apocalypse, and various themes of how humanity adapts, changes, or appeals to its better angels. 1 and 2, while very much typical “hero stories”, also left leeway for severe Machiavellian tendencies on the part of the player without it breaking the game. The Beth Fallouts don’t even get that right, with the Lone Wanderer being constantly berated if he’s bad rather than actually feared, and the Sole Survivor being another “blank slate” but one that isn’t even done well enough to have any actions, good or bad, have gravity.
