... I'm just curious to know who the -first- richest person in the wasteland is.
Right now....Mr. House. He blew 900,000 caps on retrieving the chip alone.....I don't see how the courier could get out of Sierra Madre with more than about 550-600,000 caps worth of swag. I got out with around 500,000 in gold and pre-war money....counting weapons and armor a little over 500,000 + the ~4000 chips I elected not to cash in for pre-war money before leaving. I'm sure my hoard rivals any of the NCR Brahmin Barons but House probably has 5-10x that much or more, not counting the massive revenue stream from the casinos.
The question I'd have is what to do with it? One project that seems worthy would be to resurrect the Bison Steve....with that kind of money the building could be rehabbed properly, and even the roller coaster restored to function. And if the Deathclaws and Powder Gangers are eradicated the Long 15 would be "the" route to Vegas from the NCR again.
