There is no DLC to buy. A new install now, or update, will include everything.
The stuff people buy are mainly: Fallout 1st. Which allows your own private world where you can invite people, and a scrap box for unlimited materials storage. It's absolutely not needed to still get the full experience. It's the kind of thing you but after 100 hours or so where you realise I am gonna be here for 100's of hours more and want to hoard.
Fallout's MP is done great. No pressure, do your own thing, or get sweaty and kill people, get a bounty on your head and be a wasteland murderer. Everybody on server gets a notification and has you marked on their respective maps when you do.
You can set your character to 'passive', that way you will never need to worry wbout PVP, accidental or otherwise.
Once you get to level 50, game and all events are accessible. Before that you will need to be carried.
'I Have Become Death' is my most memorable and satisfying achievement in a video game.
It's a game for the meanderer, in no rush gamers. Even after giving everything away to encourage staying away, I still go back to it evry now and then, particulalrly when different events are in the cycle. Fasnacht, Meat Week, Alien Invasion etc
Yes I am Ultra Fanboy.
