Basically my mods for Fallout are all incredibly cluttered and I have loads of mods installed that I don't actually use or need, so I wanted to know...

If you had to choose 5 mods to install, and no more, what would they be?  

*So far I'm thinking*
1. Project Nevada
2. Monster Mod
3.
4.
5.

- Hitman 1st person overhaul mod
- Hitman Animated Ammo & Weapon Condition Checking
- -=R.S.A=- Tactical weapon mod
- VGU Armor Sampler 3
- Flashlight NVSE (and the required mods)

Nuff said

That's a pretty good choice, it isn't incredibly flashy but still adds a whole lot more to the game.
This shall be one suggestion to consider

fallout character overhaul
a Christmas fallout
willow
monster mod
caesuras new regime

Caesars New Regime and Christmas fallout? Hmm I haven't heard of those before, I'll have to check those out

Tale of two wastelands
Project Nevada
Hitman animation replacers
Someguy series
Monster Mod

Oh monster mod That's one I was definitely thinking of adding

My most required 5 are:
Alternate Start
Sprint Mod
Fellout
Bullet Time
Vurt's WFO

My most used top 5 are:
Bridge Side Haven
H4DMR
Mojave Sandy Desert
Daryl Dixon Companion
Dragbody's Armor & creature Packs (Personal mod replacing armors of npc's and factions, and creature replacers through out the Mojave)

Bullet time and sprint are added through Project Nevada so you can count those as 1 mod, leaves room for something else.

I don't count those as one mod, I use two separate mods. I don't use Project Nevada.

Well fair enough then, mind if I ask why?

My load order is plagued by heavy mods, as I create a lot myself and usually have around 40-50 of my own active to test them and improve them. Any more mods, even as cool as PN, would probably cripple my game eventually. I have texture packs and more, and when I did use PN I had some stutter appear, probably just a simple mod conflict forcing an overwrite somewhere on a gamemode script.

I get by fine without it at the end of the day, and I never found a personal need to re-install it.

1. RSA Tactical Weapons

2. JoO's Modern Armoury

3. Project Nevada

4. NCR Faction Overhaul

5. Willow

Those are my current top 5 mods, As I'm really fickle, They'll change sooner or later.

Yeah same, I'm not too good with picking favourites, so this will most likely be used for a while and then I'll change it up for something else

Compred to Skyrim I hardly have any FNV mods installed, just a few companion mods - such as Willow and Delilah.
But perhaps GUN can change that

The Star Wars mods by Cpt.Rex They look absolutely fantastic, they are pretty much the reason I came to GUN I can't wait to be able to finally use them.

1.The advanced recon series
2.Vanessa/Willow
3.Project Nevada
4.Dragboy's misc. armor mods
5.Battlefield 4 weapon mod pack

1. Project Nevada
2. Everything Hitman makes
3. EVE
4. WMX
5. Weapons of the New Millenia

mine will be the following:

1: FNVRWL + dark night if you like (find it really good even with the dark night option though)
2: simple street lights + lighten up is awesome if you tweak them a little. much better than the eco-city imo.
3: awop + momod patch. crazy spawns if your rig can handle it.
4: hardcore visual effect
5: randomtraps quite fun even though it can be a lot more crazier imo.

1) Project Nevada
2) FCO, faces look too ugly otherwise
3) Weapons of New Millenia
4) merged texture packs of NMC, EWI, etc
5) Gun Behavior Mod Merge for increased combat realism
