Fallout New Vegas is one of the greatest games of all time. I like just walkin' around the beginning area and running away from radscorpions. I like talking to the same NPCs and doing the same roleplaying as I did in my last run. I always go :o when more of the world and characters are revealed. Never gets old!
Ships are probably left/right fixed unless otherwise stated.
In current year, you may NEED some mods in order to run New Vegas on a modern machine. Even at release, NV was very buggy, crash-prone and nigh unplayable.
You may also want some fun mods to add new quests, or femboy legionairies to the game. Those are cool too.
My NV Modlist is on a separate page cuz it's so long.
Clean, curated mod packs are a great starting point to see which mods are well-known to work well, and play good with other mods! They'll also walk you through any errors you may find if you try to install stuff yourself the first time.
Once you have a good base set-up from modpacks, you may wish to pick and choose mods for your own taste.
I like that we can choose alternatives to one big site! It's nice to spread things around and choose the policies that work best for our own needs.
