Do you defuse the bomb and save Megaton? Or let it explode and take the town with it?

Fallout 3's big decision is memorable for its stark simplicity and big consequences. It should be an easy choice and it certainly seems open-and-shut on the surface. What monster would let a city, and all the people in it, burn? Well, the wages of sin is wealth. Defuse the bomb and you'll earn 300 caps and an apartment in Megaton. But let it explode and your haul increases to 1,000 caps, plus a luxe penthouse in Tenpenny Tower where you can kick your feet up.

Even with incentives, though...
