Fallout NV, Lucky, Sawed off Shotgun and the Ranger Sequoia and for Fallout 3 the Sawed off Shotgun as well, the MIRV, and with Point Lookout the double barreled shotgun.

the Hunting rifle is so OP and looks badass

The combat shotgun was like my signature vanilla weapon form Fallout. Because of Desmond Lockheart.. OP, blows stuff up with bloody mess

Easily, EASILY the medicine stick. OP to such an extent that I used it for killing deathclaws, mainly because it took 2 ~ 3 shots to the face, and 1 shot for essentially everyone else in the game except for people with power armor but nobody really had power armor except for me, and for relatively cheap bullets that were common, it was my go-to.

If I was going for weapons I like the look of the most, it'd be the Mysterious Magnum.

Paciencia, definetly. The overall design and the fact that you need patience to aim so you make the shots count just makes it my favorite.
Always liked the idea of a rifle with a flag wrapped around the stock.

Fallout 3: Chinese assault rifle. Just because it sounded and felt like it could seriously do some damage. And it did.
Fallout new vegas: "That Gun" and "Bumper Sword" "That gun" because of the reload sound. It just sounds awesome and "Bumper sword" because it really fits legion characters. use "player.setscale 1.06" and you're taller than most people and can weild a huge sword to crush people.

In New Vegas, hands down, the .45 Auto Pistol. I have no idea why either. I just fell in love with using it. Second to that would be the Anti Material Rifle. It was perfect for me for taking out Deathclaws with explosive ammo.

I really love the 12'7 pistol silenced, its my favourite because of the rate of fire, damage, precission and of course, the ability to stay stealthy when blowing up almost every kind of enemy head from a close to medium distance

I love the single shotgun. Don't know why, as it's not a great weapon. There's something so satisfying about running up to someone and blowing their head off.

Marksman carbine. So versatile, and ammo is so common. Take a deathclaw by surprise and it'll never reach you. Not to mention its one sexy looking gun.

The Fatman is my favorite vanilla weapon, who doesn't love nuclear destruction

My favorite weapon has to be the Chinese Assault Rifle from Fallout 3. Who doesn't want to fight those commies with their own weapons? (also 5.56 ammo isn't too hard to find)

I'd have to go with the Ranger sequoia. I did get a re-texture mod for it cause I rather not have reminder's it's of NCR Origin. (Going for a Desert Ranger playthrough)

The Flamer, Even though I rarely will ever use it. I still find it to be my favorite weapon.

That Gun. I was going to say the sturdy caravan shotgun, but it's a POP weapon and it's more situational, whereas once I get my hands on That Gun it becomes my go-to pistol pretty much for the rest of the game.

Plasma rifle, seriously. I know that probably sounds a little too simple, but I just love turning things into piles of goo.

Wazer Wifle from fallout 3 i love the kid that gives it to you i now feel bad about laughing at a fake kids speech inpedament... i know i slaughtered that word
