"Maybe" was about being alone, and the Vault Dweller was definately very alone at the end of the game. "A Kiss to Build a dream On" might have been about the GECK/Kiss thing, with the Dream being a future, which also makes sense in that the line "Give me a Kiss before you leave me," could be interpreted as the Vault 13 residents leaving the GECK, which, by a cosmic coincidence, is what saved Arroyo. Just another thought there.
I like EraserMark's idea, but what if you had that 'robbing the gas station' thing, only instead of the military kickin' their arse, they look up and see shadows. Then it's WOOOOSH... BOOM!!! Then it zooms out and it's a PIPBoy screen, and then you see a hand switch the PIPBoy off and the narrator begins his little "war never changes" blurb.
