That sounds a lot like how I replay most games actually. It's kinda tragic because choices tend to mean a lot in CRPGs but I have just accepted it now and watch alternate stories and endings online.
Actually Fallout was the game that got me into modding heavily because I was tired of the traders getting killed so I found a mod to make them almost unkillable.
I don't mod much, but I don't think I even could on PS3. Not quite sure how that works. I just give the traders better guns and armor, plus a pre-war hat for Doc Hoff, so he looks more like Walter White. Basically, I play as myself, a chaotic neutral cannibalistic housewife/scientist who collects teddy bears and befriends all the animals. House is littered with drugs, bed is covered in teddies, fridge is filled with dead bodies. Tis a shame that Animal Friend doesn't work on deathclaws....
I'd like to get into modding and such, but I'm about as tech-savvy as an earthworm. Actually, that's part of why I joined Phuks, to maybe poke around and learn a thing or two. Other sites are just too big for me.
Just a heads up: That link I sent in my previous reply. For years that site has been by default you had sign up and specifically opt in to see NSFW stuff but it seems that's changed so be careful opening it because I can see some iffy stuff just in the thumbnails.
There was talk about mods for games like Fallout 4 on consoles but it seems there's nothing for Fallout 3.
Some of the mods for Bethesda games are awesome and built especially for people who like to roleplay.

Unfortunately all for PC.
There are a lot of mods that also optimist the games to run on laptops and low powered pcs if those are an option for you.
I play the game in a very particular order, only going certain places when I reach certain levels and have certain perks. For example, I don't go to Megaton until I have at least 5000 caps and an Explosives skill of 25, so I can disarm the bomb, get my house, and buy all furnishings (Explorer theme, workbench, infirmary, laboratory) all in one day or so. And I don't go to the scrapyard to get Dogmeat until I have my house in Megaton, because I want a nice home for my pup. No Andale until I have the Cannibal perk, no Yao Guai tunnels until the Animal Friend perk, and I test the mole rat repellant BEFORE the Animal Friend perk so I don't gotta kill my rat friends.
BUT I still like having a semi-realistic path of travel, not just bouncing around the map all nilly-willy. So I color-coded the map to mark where I do and don't go at certain levels. It's much less tedious than it sounds, and no, I don't get this nitpicky about other games. Fallout just has so much to do in one playthrough.
