Doomfullord
The Lord Full of Doom
I would probably say Brazil is lore-breaking, to an extent on what it does to canon. It's it's own canon. It's not a mod that really sort of adds to the game, it aims to try and be a different fallout game using New Vegas assets. However, is it lore-friendly? You can break lore heavily and still be friendly I think. Brazil very much tries to be in the same vein as Fallout, but takes it's own history and ideas into a game. It's its own beast and worth a try, at least probably when their finished.
