For those who are interested by an immersive role-playing start in FNV, I created some balanced archetypes:

Engineer: [IN, PE] Repair, Science, Explosives
Gunner: [AG, PE, IN] Guns, Explosives, Repair
Guru: [CH, EN, PE] Speech, Survival, Energy Weapons
Hustler: [PE, CH] Lockpick, Speech, Barter
Infiltrator: [EN, AG, PE] Unarmed, Sneak, Lockpick
Medic: [IN, EN] Medicine, Unarmed, Science
Mercenary: [PE, CH, FO] Energy Weapons, Barter, Melee Weapons
Saboteur: [PE, AG] Explosives, Lockpick, Sneak
Scavenger: [CH, IN, AG] Barter, Repair, Guns
Scientist: [IN, PE, CH] Science, Energy Weapons, Speech
Scout: [AG, EN] Sneak, Guns, Survival
Tribal: [EN, FO, IN] Survival, Melee Weapons, Medicine
Warrior: [FO, IN, EN] Melee Weapons, Medicine, Unarmed

What class do you prefer? Share your builds for every Fallout game (it's a shame they removed skills in F4...)!

Hey @LeoMen14! Nice list of archetypes.

My scavenger character: [CH, IN, PE] I do prefer energy weapons instead of powder weapons because of the use of "batteries" (roleplay). I invest points in Barter, Repair and science too, to access terminals and such. Besides lockpick, of course.

Hi @"professorleo"
Actually perception instead of agility totally makes sense in a role-play perspective because the scavenger character needs to detect valuable objects and potential threats while keeping safe. I tended towards guns because these weapons are far more common and easy to manipulate. But we know the prospector is always looking for hidden treasures... So the choice belongs to the player.
Yeah, batteries. It makes me think to the Flashlight NVSE mod in which you can choose an optional battery requirement. Great for immersion.
I saw a few screenshots of your character in another topic but I didn't see what energy weapons you usually use. I'm curious now...

I guess I'd call my go-to character a Tinkerer: [IN, PE, LK] Repair, Science, Survival

Spoiler:

Hy @LeoMen14! My character uses the Wunderwaffe rifle as his weapon of choice. In close combat he uses the laser rifle from the FO4 weapons by @Ansaar. When he is out of the power armor and looting (i use the mod Immersive Power Armor) he uses the Microwave weapon, from Project Nevada.

Usually i would go with high charisma and then relatively even across the board, as for skills usually guns, speech and lock-pick so for your classes that would make me the most similar to hustler. However scavenger definitely seems like the most appealing class to me.

@"professorleo" This Wunderwaffe rifle really looks impressive! I think I'm gonna try it in a next playthrough. Thanks for the link!

My chars always start up with speech,guns and energy weapons, later only energy weapons cuz of the immersive VATS mod wich only allows energy weapons to use VATS, perception and agility when my level advances and i got better gear

Melee Pyschopath - Melee Weapons, Medicine (for drugs) and Survival. Theres something satisfying about beating your enemy to (literal) bloody chunks against a enemy that , usually, have the range advantage.

Lockpick, Science and Speech for me. They seem the smartest as without those skills you can not even attempt what they offer, whereas with guns, explosives, etcetera they just add bonuses and more damage and stuff.

I primarily focus on charisma, intelligence, and luck in my SPECIAL, Wild Wasteland and Skilled for my traits, and I usually focus skill points into Energy Weapons, lockpick, science, and repair. I don't think I've ever actually gotten survival above 50.

Guns, sneak, and survival for me. I tend to try and balance out my SPECIAL each time I play through.

My robot character prioritizes in energy weapons, repair, and science. As long as he can keep scrapping and repairing and recharging himself, the meatbags can all starve for all he cares.

I use a Player Character that I call The Philosopher

His first 3 Skills of Focus are Speech, Mercantile and Science

Speech is used to talk his way through situations with Characters, sometimes leading to very little effort on his part to get a job finished, or even talk his way out of a potential conflict.

Mercantile is used to make as much profit as possible from Merchants along with haggling with other Characters to get the highest payment possible for jobs

Lastly, Science is used because I consider this Character an intelligent individual and what better way to represent that than being highly skilled in Science, not to mention it helps with solutions to some jobs E.g Dr. Henry in Jacobston

Hitman/Assassin/Career Killer [AG, CH] Sneak, Guns, Barter. Quick, quiet and efficient. But, he's all about that skrilla and will not offer his services unless the contractor is willing to pay top dollar. (Think Deadshot from Suicide Squad).

Most of my favorite created characters in fnv fits this build.

Murderous psychopath is my way to go, with mods that multiply enemy spawns

Usually I roleplay as a hardcore survivalist/ gunslinger with high endurance and agility tagging guns, repair and survival but in my current playthrough I'm doing a mad scientist build with focus on low STR and PER (4 glasses) and very high INT and AG. He's addicted to mentats, likes energy weapons but he's a coward so he relies heavily on robots, terminals, turrets and Arcade Gannon.

1st Character: Courier 6 (for vanilla playthrough)
2nd Character: Col. Abigail Adams (NCR Playthrough)
3rd Character: Fabius Maximus (Legion Playthrough)
4th Character: Mr. Palafox (House Playthrough)
5th Character: myself (Yes Man Playthrough)
6th Character: Arthur (first half of the game favors NCR, after encountering Silus (his friend from the past) and torturing him, turns his back on the republic and murders all trace of NCR in the region)
7th to 12th: people out of time and victims of the first battle of hoover dam
13th: Boba Fett because hella

Assassin style with sharp knives and throwables or commando with 2 handed weapons mainly smgs

Yeah, FO4 was sure to follow what happened to Skyrim (making the game simple to extend the public), and because of that i do not really care to take perks, actually i go on playing and when i look at it, i have 4 points there. I mostly only spend them to pick requisites.

But, to the class.

As i like a lot the Roleplaying part of the RPG, i do not care much into stats and everything. But in FO3 and FNV my characters were all women of science. They had big INT and CHAR, and were good at computers and with medicine. Usually they knew a bit about repair, small guns and rifles, sneaking and lockpick.
My characters in FO4 are in the same boat. The last one i took a bit more of STR only to carry more things (i love carrying junk and lots of armors -from mods- around).
