Find a non contaminated place where I can actually grow food, and try to settle there. Over time I would assume you can herd cattle and even train some dogs. But most likely I'd suffer a lack of food, since I would be growing the "good stuff" in order to mantain my sanity hahaha.

Also: sneak FTW and absolute lack of morals or values in my offensive approach. Them kids with a bullet in their hip make for nice bait to raid any human coming close to my territory

If I was in Washington D.C I would join the Brotherhood Of Steel, If I was in Vegas Probably The NCR, That's how I played those 2 games. Not like you had a choice in Fallout 3 anyway but they are The number one faction after the enclave were destroyed

Be a merchant or a diplomat ... in New Vegas and cut ties with both the legion and ncr, if one faction is winning i will join them, in a non-aggressive way. and in DC i will be a merchant ...

Become part of the NCR one way or another, and mostly work as a Sniper or Ranger; thought I wouldn't mind working Freelance either

I would run straight to the shops (which are next door to me) and take as much food as I can and then barricade my house as people will try to kill me cause I have food. Then I will hook up with my friend cause he has guns and swords and stuff.

I would love to be a wasteland badass just gunning down ghouls and mutants as I see fit but I'd probably die in my first 5 minutes out in the wasteland.

I would probably try and a find a kung fu hermit that has survived and become one with the fallout, Making peace across all the land.

I would starve to death or be killed and eaten by Raiders.

I would immediately go and join the Brotherhood of Steel as a scribe. Best tech in the wastes outside of the Enclave, and generally well supplied and protected. I know full well I'm not cut out to survive on my own or be a Paladin, but I'm good with tech and the Brotherhood can always use more tech-savvy people. Plus, I'd rather be protected by a bunch of dudes in power armor with laser than go join the NCR or something like that.

Ideally, I'd join the Brotherhood in the DC area, since they're less xenophobic than some of the other chapters.

if I lived in the fallout universe, hell ill be going around looting, shooting up places and doing all sorts of random stuff.

also ill probably be Eli from the book of Eli, being that one badass just walking around head high and nothing to be afraid of, not even death claws can get in my way

I would honestly gather much as supplies as I need and keep traveling. If I hold up somewhere There's bound to be bullshit coming ethir killing me or kicking me out.

I'd get a comfy job at the Ultra Luxe and pray I'm not the one being eaten.

I'd try to set up a secret hideout, and wander the wasteland trying to help people in any way possible.

I'd try to work for the Gun Runners as a gunbuilder. I'd never go hungry or out of work since everyone wants guns, and they don't come cheap.

If you live in fallout would get work in casinos.It is safe and well-paid and have women ... k

Good question! If I came out of the vault, I would head to public libraries and the city hall and scavenge through government documents about city plans, so that I could know what building are out there and their interiors, possible resource locations and so fourth. Afterwords, I would take a sleeping bag, backpack and some few essential survival equipments (before the apocalypse, I already have a repeater cross bow, so I would have that handy). Afterwords I would acquaintance myself with all of the factions and not really join one right off the bat, I would wonder on my own until I know I found a trust worthy companion, find a small stable city and get a job where I get to travel around so that I can familiarize myself more about the creatures that dwell. I would try to hone my skills with weapons, and sneaking as well. After I have determined who are the baddies of the wasteland and their power, I would try to find their weaknesses, and work together with other factions to bring them down and hopefully try and bring order to the world again. Sort of what the game already does lol!

If I lived in the Fallout Universe I would have joined the Followers of The Apocalypse, but not as a medic, but as a scavenger.
I would love to go looting in the wastelands and bringing back some good stuff (from food to ammo to pre-war books) for improving living conditions in Freeside and for those who need help.

Get mauled to death by 1000 radroaches while trying to drink toilet water

Well if I could survive long enough I could forsee myself becoming something like a Randall Clark AKA the Survivalist. Surviving and helping from a distance, granted Im sure Id be dead within the first few days haha

Basically become "Mad" Max Rockatansky. Wander from place to place with my dog (or cat?) as company, finding gas, all that.
